XCVIII. Oracle 函数


本类函数使用 Oracle Call Interface(OCI)使用户可以访问 Oracle 10,Oracle9,Oracle8 和 Oracle7 数据库。支持将 PHP 变量与 Oracle 占位符(placeholder)绑定,具有完整的 LOB,FILE 和 ROWID 支持,以及允许使用用户提供的定义变量。


使用本扩展需要 Oracle 客户端库。Windows 用户需要至少 Oracle 8.1 版才能使用 php_oci8.dll

安装所有所需文件最方便的方法是使用 Oracle Instant Client,可以从此处得到:http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html。Instant Client 不需要 ORACLE_SID 或 ORACLE_HOME 环境变量被设定。不过可能还是要设定 LD_LIBRARY_PATH 和 NLS_LANG。

在使用本扩展之前,请确认已经为 Oracle 用户和 web daemon 用户正确设置了 Oracle 环境变量。这些变量应该在启动 web server 之前设定。下面列出了需要设置的环境变量:






对于较少用到的 Oracle 环境变量例如 TNS_ADMIN,TWO_TASK,ORA_TZFILE 和各种 Oracle 全球性设定例如 ORA_NLS33,ORA_NLS10 和 NLS_* 等变量请参考 Oracle 稳当。

在为 web 服务器用户设置环境变量之后,还需要将 web 服务器用户(nobody,www)加到 oracle 组中。

I如果 web 服务器不能够启动或者在启动的时候崩溃: 检查 Apache 是否连接了 pthread 库:

# ldd /www/apache/bin/httpd
    libpthread.so.0 => /lib/libpthread.so.0 (0x4001c000)
    libm.so.6 => /lib/libm.so.6 (0x4002f000)
    libcrypt.so.1 => /lib/libcrypt.so.1 (0x4004c000)
    libdl.so.2 => /lib/libdl.so.2 (0x4007a000)
    libc.so.6 => /lib/libc.so.6 (0x4007e000)
    /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

如果 libpthread 没有列出,必需重新安装 Apache:

# cd /usr/src/apache_1.3.xx
# make clean
# LIBS=-lpthread ./config.status
# make
# make install

请注意在像 UnixWare 之类的某些操作系统中,使用 libthread 代替了 libpthread。则 PHP 和 Apache 必须使用 EXTRA_LIBS=-lthread 配置。


这些函数的行为受 php.ini 的影响。

表格 1. OCI8 Configuration Options

oci8.old_oci_close_semantics"0"PHP_INI_SYSTEMBecame available in oci8 module version 1.1


oci8.privileged_connect boolean

This option enables privileged connections using external credentials (OCI_SYSOPER, OCI_SYSDBA).

oci8.max_persistent int

The maximum number of persistent OCI8 connections per process. Setting this option to -1 means that there is no limit.

oci8.persistent_timeout int

The maximum length of time (in seconds) that a given process is allowed to maintain an idle persistent connection. Setting this option to -1 means that idle persistent connections will be maintained forever.

oci8.ping_interval int

The length of time (in seconds) that must pass before issuing a ping during oci_pconnect(). When set to 0, persistent connections will be pinged every time they are reused. To disable pings completely, set this option to -1.

注: Disabling pings will cause oci_pconnect() calls to operate at the highest efficiency, but may cause PHP to not detect faulty connections, such as those caused by network partitions, or if the Oracle server has gone down since PHP connected, until later in the script. Consult the oci_pconnect() documentation for more information.

oci8.statement_cache_size int

This option enables statement caching, and specifies how many statements to cache. To disable statement caching just set this option to 0.

注: A larger cache can result in improved performance, at the cost of increased memory usage.

oci8.default_prefetch int

This option enables statement prefetching and sets the default number of rows that will be fetched automatically after statement execution.

注: A larger prefetch can result in improved performance, at the cost of increased memory usage.

oci8.old_oci_close_semantics boolean

This option controls oci_close() behaviour. Enabling it means that oci_close() will do nothing; the connection will not be closed until the end of the script. This is for backward compatibility only. If you find that you need to enable this setting, you are strongly encouraged to remove the oci_close() calls from your application instead of enabling this option.


以下常量由本扩展模块定义,因此只有在本扩展模块被编译到 PHP 中,或者在运行时被动态加载后才有效。

Statement execution mode. Statement is not committed automatically when using this mode.


Statement execution mode. Use this mode if you don't want to execute the query, but get the select-list's description.


Statement execution mode. Statement is automatically committed after oci_execute() call.


Statement fetch mode. Used when the application knows in advance exactly how many rows it will be fetching. This mode turns prefetching off for Oracle release 8 or later mode. Cursor is cancelled after the desired rows are fetched and may result in reduced server-side resource usage.

例子 1. 基本查询


= oci_connect('hr', 'hr', 'orcl');
if (!
$conn) {
$e = oci_error();


$stid = oci_parse($conn, $query);
if (!
$stid) {
$e = oci_error($conn);

$r = oci_execute($stid, OCI_DEFAULT);
$r) {
$e = oci_error($stid);

'<table border="1">';
$row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {
$row as $item) {


例子 2. 用绑定变量插入


// Before running, create the table:

$conn = oci_connect('scott', 'tiger', 'orcl');

$query = 'INSERT INTO MYTABLE VALUES(:myid, :mydata)';

$stid = oci_parse($conn, $query);

$id = 60;
$data = 'Some data';

oci_bind_by_name($stid, ':myid', $id);
oci_bind_by_name($stid, ':mydata', $data);

$r = oci_execute($stid);

"One row inserted";



例子 3. 将数据插入到 CLOB 列中


// Before running, create the table:
//     CREATE TABLE MYTABLE (mykey NUMBER, myclob CLOB);

$conn = oci_connect('scott', 'tiger', 'orcl');

$mykey = 12343;  // arbitrary key for this example;

$sql = "INSERT INTO mytable (mykey, myclob)
        VALUES (:mykey, EMPTY_CLOB())
        RETURNING myclob INTO :myclob"

$stid = oci_parse($conn, $sql);
$clob = oci_new_descriptor($conn, OCI_D_LOB);
oci_bind_by_name($stid, ":mykey", $mykey, 5);
oci_bind_by_name($stid, ":myclob", $clob, -1, OCI_B_CLOB);
oci_execute($stid, OCI_DEFAULT);
$clob->save("A very long string");


// Fetching CLOB data

$query = 'SELECT myclob FROM mytable WHERE mykey = :mykey';

$stid = oci_parse ($conn, $query);
oci_bind_by_name($stid, ":mykey", $mykey, 5);
oci_execute($stid, OCI_DEFAULT);

'<table border="1">';
while (
$row = oci_fetch_array($stid, OCI_ASSOC)) {
$result = $row['MYCLOB']->load();



例子 4. 使用存储过程

// by webmaster at remoterealty dot com
$sth = oci_parse($dbh, "begin sp_newaddress( :address_id, '$firstname',
'$lastname', '$company', '$address1', '$address2', '$city', '$state',
'$postalcode', '$country', :error_code );end;"

// This calls stored procedure sp_newaddress, with :address_id being an
// in/out variable and :error_code being an out variable.
// Then you do the binding:

oci_bind_by_name($sth, ":address_id", $addr_id, 10);
oci_bind_by_name($sth, ":error_code", $errorcode, 10);



OCI8 扩展提供了 3 个不同函数来连接 Oracle。取决于用户来使用对自己的应用程序最合适的函数。本节的信息有助于用户作出合适的选择。

连接到 Oracle 服务器从所需的时间上来讲是个相当花费的操作。oci_pconnect() 函数使用了一个连接的持久缓冲区,可以被不同的脚本请求重复使用。这意味着通常在每个 PHP 进程(或 Apache 子进程)中只需要连接一次。

如果应用程序连接 Oracle 时对每个 web 用户都使用了不同的认证信息,则由 oci_pconnect() 使用的持久缓冲区就用处不大了,因为随着并发用户的增加,到某个程度后会由于要保持太多的空闲连接而对 Oracle 服务器的整体性能起到逆反的影响。如果应用程序是这样的架构,建议要么用 oci8.max_persistentoci8.persistent_timeout 配置选项(此二者可以使用户控制持久连接缓冲区的大小和生命周期)来协调应用程序,要么用 oci_connect() 来连接。

oci_connect()oci_pconnect() 都使用了一个连接缓冲区。如果在某个脚本中用同样的参数多次调用 oci_connect(),则第二个和之后的调用会返回已有的连接句柄。oci_connect() 使用的连接缓冲区会在脚本执行完毕后或者明确地关闭了连接句柄时被清空。oci_pconnect() 有相似的行为,不过其缓冲区独立地维持着并在不同请求之间都存活着。

要记住此缓冲特性,因为它使两个句柄没有在事务级隔离开来(事实上是同一个连接句柄,因此没有任何方式的隔离)。如果应用程序需要两个独立的,事务级隔离的连接,应该使用 oci_new_connect()

oci_new_connect() 总是创建一个到 Oracle 服务器的新连接,不管其它连接是否已经存在。高流量的 web 应用应该避免使用 oci_new_connect(),尤其是在程序最忙的部分。


表格 2. 用 oci_bind_by_name() 函数绑定参数时支持以下类型

SQLT_NTY映射到一个来自 PHP collection 对象的本地 collection 类型,例如由 oci_new_collection() 创建的。
SQLT_BFILEE映射到一个本地的 descriptor,例如由 oci_new_descriptor() 创建的。
SQLT_CFILEE映射到一个本地的 descriptor,例如由 oci_new_descriptor() 创建的。
SQLT_CLOB映射到一个本地的 descriptor,例如由 oci_new_descriptor() 创建的。
SQLT_BLOB映射到一个本地的 descriptor,例如由 oci_new_descriptor() 创建的。
SQLT_RDD映射到一个本地的 descriptor,例如由 oci_new_descriptor() 创建的。
SQLT_NUM将 PHP 参数转换为 C 语言的 long 类型,并绑定为其值。
SQLT_RSET映射到一个本地的 statement 句柄,例如由 oci_parse() 创建或从其它 OCI 查询取得的。
SQLT_CHR 以及任何其它类型将 PHP 参数转换为字符串类型并绑定为字符串。

表格 3. 在从结果集中取得列时支持以下类型

SQLT_RSET创建一个 oci statement 资源来代表指针。
SQLT_LNG限制为 SQLT_CHR,返回为字符串。
SQLT_LBI限制为 SQLT_BIN,返回为字符串。
任何其它类型限制为 SQLT_CHR,返回为字符串。

To fsegtrop at estiem dot org:

Thank you for the note about the DOS/Unix line-endings.  My boss gave me his copy of tnsnames.ora from his Windows machine for my use on my Linux workstation.  I spent three hours trying to figure out why, and researching Oracle connections.

A simple dos2unix command on my tnsnames.ora file fixed the problem.

estoreic (note from 15-May-2006 10:54) is right.

there seems to be a problem with the oci8-api-functions in php 4.4.x.

there are error-messages like these in the error_log:
child pid 22297 exit signal Segmentation fault (11)
*** glibc detected *** double free or corruption (out): 0x00000000019f4730 ***
*** glibc detected *** double free or corruption (!prev): 0x0000000001111d90 ***
*** glibc detected *** corrupted double-linked list: 0x0000000001111d50 ***

using php 4.4.x with oracle 10.x is impossible, until you do the following:
1. download latest oci8-package from http://pecl.php.net/package/oci8
2. extract package somewhere
3. go to php-4.4.x-source directory
4. rm -rf ext/oci8
5. cp extraceted oci8-1.2.x directory to/as ext/oci8
6. make distclean
7. ./buildconf --force
8. ./.configure (with the options you need)
9. make
10. only for x86_64:
create pear-install.ini:

memory_limit = 128M      ; Maximum amount of memory a script may consume (8MB)

11. edit Makefile:
PEAR_INSTALL_FLAGS = -n -dshort_open_tag=0 -dsafe_mode=0
PEAR_INSTALL_FLAGS = -cpear-install.ini -dshort_open_tag=0 -dsafe_mode=0

12. make install

have fun!
oracle connections will work now!

We were having performance issues caused by Segmentation Faults on pages using Oracle.

An example of the Seg faults appearing in Apache's error log is:
*** glibc detected *** free(): invalid next size (fast): 0x0969ef30 ***
[Mon May 08 09:41:51 2006] [notice] child pid 3065 exit signal Aborted (6)


[Mon May 08 09:48:58 2006] [notice] child pid 4747 exit signal Segmentation fault (11)

Our issue was due to a problem with OCI8 module in PHP (latest version 4.4.2).

Our solution involved recompiling PHP with the latest PECL OCI8 extension which can be downloaded from:

All segmentation faults and performance issues stopped once PHP was recompiled with OCI8 1.2.1.

If you are experience performance issues and/or seg faults I would recommend recompiling PHP with the latest stable OCI8 extension.

Dropping support for Oracle 9i clients on Windows is a huge mistake! Most people in production environments can't just slap another oracle_home on their box just for php traffic.

The Instant Client is aimed at desktop users, not servers, and is the last thing an experienced Oracle person would be installing.

The code works fine in 5.1.3RC2, so I guess we're stuck on that version until the issue is addressed properly.

For installation and enabling support of OCI8, I highly recommend Zend Core for Oracle from Zend.  I had almost a month's worth of trouble trying to get OCI8 working until I found that, and it was a piece of cake with that.

To compile PHP 4.4.2 with OCI8 / Oracle 9i / AIX 5.2 (64-bit) / GCC

PHP will automatically compile against the Oracle 64-bit libraries, which PHP being a 32-bit app, will cause "make" to fail (though it will configure fine). Here's how to avoid this:

1. replace your PHP's ext/oci8 directory with the latest ext/oci8 directory downloadable from PECL - then remove the old directory entirely

2. rebuild configure by running:

./buildconf --force

...in PHP's root directory. This will rebuild the configure script.

3. using a tool like sed, in your configure file replace all instances of /path/to/oracle/lib with /path/to/oracle/lib32 - note, this may require GNU's autoconf, m4 and gnumake.

4. export LD_LIBRARY_PATH=/path/to/oracle/lib32

5. ./configure --with-oci-8=/path/to/oracle (and any other options)

Then, the usual make and make install.

# here's what it took to get it going for me on rhel4 on x86_64 w/ 10gr2 and php5.0.5
# hopefully this will save someone a little grief
# first you must install the 10.2 full client in /app/oracle/product/10.2.0/db_1
# follow all the instructions. This part will be a bitch.

# install the instantclient basic and sdk like this
mkdir -p /usr/lib/oracle/
unzip -jd /usr/lib/oracle/ instantclient-basic-linux-x86-64-
mkdir -p /usr/include/oracle/
unzip -jd /usr/lib/oracle/ instantclient-sdk-linux-x86-64-

# make the full client use instantclient's files
cd /app/oracle/product/10.2.0/db_1

Apache 1.3, Oracle 9.2, PHP 5.1.2 on Windows XP Pro.
Very weird behavior with php_oci8.dll coming with the full windows build (I downloaded yesterday...). Couldn't get any of the examples to work, it appears Apache crashes on oci_parse, but not so if I program "C style":

  while this doesn't work:
= oci_connect("scott","tiger");
$parsed = oci_parse($db_conn,"select * from emp"); <-- Apache crashes on execution of this statement
// etc...

  this does:

function main($connection)
$parsed = oci_parse($connection,"select * from emp");
$r = oci_execute($parsed, OCI_DEFAULT);

$db_conn = oci_connect("scott","tiger");



Took me the whole day, then I found Francesco Marsan's note (THANKS!) dated February 9th, 2006... and indeed, downloading from http://pecl4win.php.net/ext.php/php_oci8.dll solved the problem instantly.

To install this in gentoo linux you will need to do some weird stuff:

-  Make sure you have this use flags set: "dba cli pcre xml zlib oci8-instant-client"
- Unmask PHP (5.1.1) by placing "dev-lang/php ~x86" in /etc/portage/package.keywords
- Unmask oracle-instantclient-basic ( by placing "dev-db/oracle-instantclient-basic ~x86"
- Download oracle files from "http://otn.oracle.com/software/tech/ oci/instantclient/htdocs/linuxsoft.html" (You have to make an account and login, in order to download the packages:

   * instantclient-basic-linux32-
   * instantclient-sdk-linux32-

- Place the downloaded packages in "/usr/portage/distfiles"
- "emerge apache dev-lang/php5" (If you done right, the build for the instantclient will be selected automaticly.
- Configure your "/etc/conf.d/apache2" to make sure you have "-D PHP5" in your "APACHE_OPTS"

Here are some tips on getting the instant client to work with php:

I am using Fedora Core 3 and php-5.1.2 on x86.


Configuring php:
./configure --with-oci8=instantclient,/usr/lib/oracle/10.xxx/client/lib/
This path will change if you unzip it isntead of using the rpms. Make sure it points to where libclntsh.so is installed.

Configuring apache:
The following lines need to be in your .../apache/bin/envvars file:
LD_LIBRARY_PATH="/usr/lib/oracle/10.xxx/client/lib/: /opt/apache2/lib:$LD_LIBRARY_PATH"
You will need to modify the paths to the oracle instantclient libs and to apache. In addition, the language will need to be modified if not US English.

TNS Names and Oracle:
Put the tnsnames.ora and sqlnet.ora files into the same directory as libclntsh.so.

Restart apache and you should be able to connect.

The error message "There is something wrong with your system - please check that ORACLE_HOME is set and points to the right directory" is somewhat deceptive in that it can be emitted even when ORACLE_HOME is correctly set, but that there is a connection failure when the OCI8 extension uses the Oracle OCI API.  This API requires access to several files in the Oracle distribution which, at least in the 10g release 2 distribution, are not available to 'others'.  It seems this may be the reason that we are directed to give oracle 'oinstall' group access to the apache user.  For those who do not consider this a good idea, the solution is to grant 'other' access to the files.

I used the following script (YMMV) ....

export ORACLE_HOME=<your-Oracle-home-here>
chmod o=x $ORACLE_HOME/network
chmod o=x $ORACLE_HOME/network/admin
chmod o=r $ORACLE_HOME/network/admin/tnsnames.ora
chmod o=r $ORACLE_HOME/nls
chmod o=r $ORACLE_HOME/nls/data
chmod o=r $ORACLE_HOME/nls/data/*
chmod o=x $ORACLE_HOME/oracore
chmod o=x $ORACLE_HOME/oracore/zoneinfo
chmod o=r $ORACLE_HOME/oracore/zoneinfo/timezlrg.dat
chmod o=r $ORACLE_HOME/rdbms
chmod o=r $ORACLE_HOME/rdbms/mesg
chmod o=r $ORACLE_HOME/rdbms/mesg/*

The ORACLE_HOME environment variable *IS* required, but I found no need to set the others (again, YMMV).

To discover the files referenced by your OCI8 scripts, you can open the security by giving apache group access to the Oracle directories, touching some temp file and using 'find' to discover the files which have been accessed.  Try using...

find . -anewer <my-touched-temp-file> -print

If you experience Apache crashes on a Windows platform with PHP 5.1.2 while trying to access Oracle, try exchanging the php_oci8.dll that comes with the distribution, with the one that is on http://pecl4win.php.net/ext.php/php_oci8.dll. After much trouble while trying many install options this finally solved my issues and worked fine.

PHP 5.1.2 was the first PHP release to ship the "re-factored" OCI8 1.1 driver.

The configuration options for the re-factored driver have changed, particularly for building with Oracle Instant Client. Some older articles and documentation are now obsolete.  Run ./configure --help to see the new syntax.

User's of PHP prior to 5.1.2 can install the re-factored driver from http://pecl.php.net/package/oci8 or http://pecl4win.php.net/ext.php/php_oci8.dll

If you're compiling php 5.1.2, and using the oracle instant client, the appropriate configure option is:

which is a change from the configure option for php 5.1.1, which was:

If you use the old one with php 5.1.2, it just silently ignores this option and the resulting php build doesn't have oracle support.

Regarding compiling with the recently updated OCI8 Extension (http://pecl.php.net/package/oci8).

I ran into problems when statically compiling, such as numerous "undefined reference to `zif_oci_***'" errors.  Since I likely won't be the only one to run into this problem, here's some helpful hints:

If you've previously compiled your php installation, first: make clean

Then replace the existing php-x.x.x/ext/oci8 directory with the latest package from: http://pecl.php.net/package/oci8

./buildconf --force
./config ..

On RHEL for PHP4 or 5...

For Oracle 9i before you compile PHP but after you install Oracle, you need to make the following symlinks:

ln -s $ORACLE_HOME/rdbms/public/nzerror.h  $ORACLE_HOME/rdbms/demo/nzerror.h

ln -s $ORACLE_HOME/rdbms/public/nzt.h $ORACLE_HOME/rdbms/demo/nzt.h

ln -s $ORACLE_HOME/rdbms/public/ociextp.h $ORACLE_HOME/rdbms/demo/ociextp.h

ln -s $ORACLE_HOME/lib/libclntsh.so.9.0 $ORACLE_HOME/lib/libclntsh.so.8.0

ln -s $ORACLE_HOME/oui/bin/linux/libcdlntsh.so.9.0

With 10g you need to make the first three and then this one:
ln -s $ORACLE_HOME/lib/libclntsh.so.10.0 $ORACLE_HOME/lib/libclntsh.so.8.0

When fetching associative arrays, use uppercase string indices. It appears the PHP OCI Library is less lenient with the field names returned by Oracle.


echo $row['field1']; // This won't return anything.

as opposed to:

echo $row['FIELD1'];

Great Solaris patch!  Finally built.  Here's some tips on connecting:

Just made this on solaris8 32bit, actually works.

1) put everything in one directory
2) unsetenv ORACLE_HOME
3) set the env vars LD_LIBRARY_PATH and SQLPATH and TNS_ADMIN(if you have it) to that directory.
4) use one of the other easy connection notations here


These env vars worked when put at the top of apachectl script as well.

To build you may have to fake it out with an ORACLE_HOME var,  but unset it later.  You may also have to fake out the build by putting header files where it is looking for them,  e.g. in the rdbms/demo directory or some such other place.

When running though,  make sure you have only the files required in only one directory.

Oracle has not put up a link to the 32bit solaris sqlplus--you have to guess it--it's there though:

...and don't forget to add ".world" on to the end of your SID. It's very common to have to specify DBNAME.WORLD to connect.

PHP 5.0.3 + Solaris 9 (UltraSPARC) + Apache 2.0.51 + Oracle 10g Instant Client

Thanks to Jakob's patch I got this combination working.  Here are some things that helped me:

1. After getting this:
ld: fatal: file /opt/oracle/instantclient/libclntsh.so: wrong ELF class: ELFCLASS64

I realized that PHP is a 32-bit application and that all 3rd-party libraries need to be 32-bit as well.  You need to download the 32-bit version of Instant Client (basic + sdk), even if you are running the 64-bit Solaris OS.

2. My patch command syntax was a little different:
patch -p0 -i php5_ociclient.patch config.m4

Thanks again to Jakob for porting the patch over to PHP 5.

Installing PHP 5.0.3 and the Oracle 10g Instant Client on Linux .

There is no need to have a full Oracle Installation on the Webserver, you only need the client.


The patches provided from Oracle are for PHP Versions 4.3.9 or 4.3.10.

Here is the handmade patch for PHP 5.0.3 :

patch -u php-5.0.3/ext/oci8/config.m4 php5_ociclient.patch
cd php-5.0.3
rm -rf autom4te.cache config.cache
./buildconf --force

Hello once again.
This time I present details on how to get Oracle Instant Client 10g ( ), PHP 5.0.3 and Apache 2.0.52 running together on Linux (I've used fedora core 1 but I can't see why this will not work for any other distro )
*Note* This is not a guide on compiling php and httpd there are plenty of guides around to do that. This just covers compiling and using the oci8 module with php.

1. Set-up and install apache-2.0.52 as per normal

2. Unpack the Oracle 10g Instant Client ( SDK + Basic, I also use the sqlplus pack to test the connection outside of apache / php )
  rpm -ivh oracle-instantclient-basic-  oracle-instantclient-devel-  oracle-instantclient-sqlplus-

3. Set env ORACLE_HOME to the clients path in the current shell your shell command may vary (this is bash )
  export ORACLE_HOME=/usr/lib/oracle/; export LD_LIBRARY_PATH=/usr/lib/oracle/;
(if you want to test if you can now get a connection to oracle using sqlplus see item 10 below.)

4. Unpack php-5.0.3 as per normal add in  --with-oci8  to the configure options. If the ORACLE_HOME is set previously then adding the directory as per "--with-oci8=$ORACLE_HOME" should not be necessary. Do this to be safe though.

5. Run the ./configure program in php source directory. Don't make it just yet though.

6. The compiler needs to find the includes oci.h + others so, from the default client install dirs, I needed to edit the php Makefile after it was configured. Open it up and look for "EXTRA_INCLUDES" and add to end of line
-I/usr/include/oracle/  (thats a capital i ) save the Makefile, then finish off compiling and installing php.  Please note im sure this will be changed in php's configure so it finds these by default in the not too distant future.

7. Create a directory /etc/oracle and place your tnsnames.ora file in there, (VERY IMPORTANT make sure you chmod your tnsnames.ora to ensure that whatever username your httpd server runs under can read the file (1.5 hours of frustration later i figured this out). I just did "chmod 0644 tnsnames.ora" it doesn't matter where you put this as long as you set the env  TNS_ADMIN to it. (IMPORTANT  TNS_ADMIN points to a directory not the actual tnsnames.ora file )

8. My system uses a /etc/init.d/httpd script to start up httpd so in that file I exported the ORACLE_HOME & TNS_ADMIN env vars before the httpd is run, oh you will need to set LD_LIBRARY_PATH as well if you not added the path to ld.so.conf
  export ORACLE_HOME=/usr/lib/oracle/; export TNS_ADMIN=/etc/oracle
9. start httpd and bobs your uncle....

10. You can test connection once the instant client rpm's are installed by using  sqlplus.  set  ORACLE_HOME as above,  TNS_ADMIN as above, LD_LIBRARY_PATH as above and if necessary.  Then  sqlplus <username>/<password>@<sid or service_name as per tns_admin file>  use sqlplus here as you would normally

PS: Thanks Oracle for the SDK,  about time !

ReCompiling PHP4 to have oracle 8 support (oci8) on Debian Linux, using the Oracle 10g client libraries. Log in as root.

php4 (source files)
php4 module (might not be required, but it's what i had installed at the time)

Oracle Client Libraries (i used Oracle 10g Server, but you should be able to use, as has been previously said, any set of the oracle client libraries from 8i onwards).
* make sure this is installed before recompiling php4.

- export ORACLE_HOME=[where u installed the oracle client]
- export LD_PRELOAD=libclntsh.so.10.1 (the version number at the end will correspond to the oracle version you previously installed. in my case, 10g is 10.1).
- vi /etc/ld.so.conf and add $ORACLE_HOME/lib to the list of paths.
then * run ldconfig to reload those changes to the system * (p.s. make sure it's the full path, and not using any environment variables. e.g. /u01/app/oracle/product/10gRDBMS is my ORACLE_HOME).

- cd /usr/src/[PHP4 Version]
in my case, [PHP4 Version] = php4-4.3.8, so path was

- vi debian/rules
these are the default compilation rules for php4. Find section labeled COMMON_CONFIG = [...] and add --with-oci8 (it should be near the top of the file).

- debchange -i (allows you to edit the change log for the versions of php. btw - you should be in the php4 source code directory). give the version id something obviously unique. don't forget to add a comment.

when all is in readyness, then you should be able to go debian/rules binary to build the debian packages required.
the deb packages are built into the /usr/src directory. and depending on the default compilation options u choose, there should be a few. find the deb package that corresponds to the main php4 module (php4_4.3.8-4.mark.1_i386.deb for me), and run dpkg -i [package name] to install it.

- vi /etc/init.d/apache and add exports for $ORACLE_HOME, $LD_PRELOAD and $LD_LIBRARY_PATH

* don't forget to restart apache /etc/init.d/apache to reload the php4 module. *

if you get an error saying something about apache cannot load libclntsh.so.10.1, file not found, check the environment variables, for both the user, and in /etc/init.d/apache and also check ld.so.conf to make sure the $ORACLE_HOME/lib path is in there, and has been reloaded (with ldconfig).

editing ld.so.conf was the part that finally got it working for me.
as you should be able to tell, the steps are pretty much the same as for all oracle versions 8i onwards, and all linux OS's. but with a few debian specific paths and commands thrown in.

For those trying to use the Oracle Instant Client 10g in a win32 environment, heres a nice easy howto. If you fully read the docs properly and understand what your reading you will be able to set it up, but if like me you want a quick easy fix, heres how I did it.

1. Download and install the Oracle Instant Client to where ever (lets say  c:\ora\client  )
2. Add your connect info, copy a previously created or provided tnsnames.ora file to the above directory.
3. Change Path in the Environment Variables area to add this directory to the path. ie.  c:\ora\client;%SystemRoot%;<and so on>
4. Open regedit and add a Key called ORACLE to HKEY_LOCAL_MACHINE\SOFTWARE
5. To the ORACLE key add a string value called TNS_ADMIN and assign it the directory above (ie. c:\ora\client )  So you end up with KEY_LOCAL_MACHINE\SOFTWARE\ORACLE\TNS_ADMIN = c:\ora\client
6. Set php to use Oci8 extension and bobs your uncle
7. Reboot.

Option 7 was required as the oci8 extension or php wouldn't pick up the path change. Also my problem was how to use other programs like sqlplus without creating extra Environment Variables etc the TNS_ADMIN / tnsnames.ora part makes that simpler and allows you to call things the same as you would before.

PS: This should apply to all the Instant Clients. I haven't tried it with any others but 10g though.

Hope this helps.

For those of you running Oracle on Linux, and running a remote box also on Linux, here's an easy way to get OCI8 working without having to install the whole Oracle DB just to get your client working.

[PS -- For the life of me, installing client libraries for Oracle really shouldn't be this hard, but it really truly is.]

Step 1.  Copy the following directories from your ORACLE_HOME directory where Oracle is installed (the database server) to your remote client server/machine:

     lib, network, ocommon, plsql, rdbms, oracore

   These contain all of the files/folders/libraries you'll need to compile OCI8 into PHP.  I put this in /home/beckman/oracle and set ORACLE_HOME as that dir.

Step 2.  Compile PHP with --with-oci8=/home/beckman/oracle (obviously using your directory, not mine).  Install, (re)start apache.

Step 3. Remove plsql and rdbms directories from ORACLE_HOME on your remote server, leaving you with lib, network, ocommon and oracore.

Step 4. Read: http://otn.oracle.com/tech/opensource/php/php_troubleshooting_faq.html

NOTE: This will only help you if you (a) have Oracle successfully running on Linux (was RH Enterprise 3 for me) and your client box is running the same OS.  I'm not sure it will work on earlier versions, but it may.  Your results should be posted here methinks!

PHP Oracle -- Compiling Oracle Support into PHP, Apache 2
Apache 2.0.48,  Php 4.3.4,  Red Hat Linux 9.0,  Debian 3.0,  Oracle 9i R2
Dave Darden  1/17/04 -- www.dardensystems.com

First install Apache 2 from source.  Instructions are at http://httpd.apache.org/docs-2.0/install.html. 
I used a --prefix=/usr/local/apache on the install. 

Install Oracle.  There is a very good Oracle install to RedHat 9.0 white paper at http://www.dizwell.com/ that goes step by step through the problems (Oracle is not supported on RedHat 9.  Oracle only supports installation on paid versions of Red Hat). 

If only an Oracle client is installed on the web server (if the database is on another machine in a multi-tier configuration) then you must install both the client and the Oracle Call Interface (OCI).  I think SQLPlus also needs to be installed.  Oracle Network Utilities and Installation Common Files were also installed.  If you cannot configure/make php because of missing Oracle library errors during configure/make, then investigate whether you have installed enough of the client pieces of Oracle on the web server machine. 

I also included a link from  libclntsh.so.8.0  to  libclntsh.so.9.0  in the $ORACLE_HOME/lib directory.  Some internet posts suggested it to prevent errors in php configure/make.  A later experience moving from RedHat to Debian confirms that it is necessary to avoid a make error on a missing lclntsh file. 

In transferring the client software from a Red Hat 9.0 web server installation to a Debian 3.0 (kernel 2.4.18) web server installation I was able to simply copy over the Oracle /u01 directory tree without rerunning the Oracle client installation.  This must be done before php is configured and compiled on the Debian machine so the oci8 libraries are available.  And of course the tips on libclntsh and environment variables must be observed as well. 

Get the php source.  This php configure line worked for me, creating an Apache 2 module, and keeping mysql and gd support.  Add other options if you need them for a given site.  For some reason, even though gd is included with php now, zlib was needed to successfully configure and make php from source when including gd.  You will need to substitute appropriate directory locations for your install of Apache, zlib, and Oracle.

./configure --with-apxs2=/usr/local/apache/bin/apxs \
--with-mysql --with-gd \
--with-zlib-dir=/usr/local \
--with-config-file-path=/etc \
--enable-force-cgi-redirect --disable-cgi \
--with-oci8=/u01/app/oracle/9i --enable-sigchild

Use an absolute path on  -with-oci8=/u01/app/oracle/9i 
(Do not use the $ORACLE_HOME path variable in the configure statement.  For some reason it does not work even when it is set properly.)

Also, set the environment variables in
/usr/local/apache/bin/envvars like so (your env var values should vary):

export ORACLE_SID="lx92"
export ORACLE_HOME="/u01/app/oracle/9i"
export TNS_ADMIN="/u01/app/oracle/9i/network/admin"
export LD_LIBRARY_PATH="/u01/app/oracle/9i/lib"
export TNS_ADMIN="/u01/app/oracle/9i/network/admin/tnsnames.ora"
export TWO_TASK="/u01/app/oracle/9i/network/admin/tnsnames.ora"
export NLS_LANG="English_America.WE8ISO8859P1"
export ORACLE_BASE="/u01/app/oracle"

I had trouble with norwegian characters using oracle 8.7.1 / php 4something and Apache 2.

The only trouble was that '?' appeared instead of the norwegian characters.

The solution to it all was to add this to the apachectl script:

export NLS_LANG="norwegian_norway.WE8ISO8859P1"
export ORACLE_BASE="/home/oracle"
export ORA_NLS33="/home/oracle/ocommon/nls/admin/data"
export ORACLE_TERM="ansi"
export ORACLE_HOME="/home/oracle"
export LANG="no_NO"

I'm not sure if all of these are necessary, but I took no change, and it works now :)

Can't compile php with Oracle 9i and apache on Solaris8?
Sun 280R

Using some of the tips below I had to add this:
(static build)


cd php-4.x.x/
./configure --with-oci8=$ORACLE_HOME --with-apache=/path/to/apache_src ..etc
make intsall

cd apache_src
(make sure environment variable is still set)
./configure  "--prefix=/usr/apache" "--enable-module=so" \
"--activate-module=src/modules/php4/libphp4.a"  ...etc
make install

Having the gcc compilier build php against oracle 32 bit libraries was the key, but without setting LDFLAGS the compiler defaults to using the 64-bit oracle libraries which cause the famous
"...wrong ELF class: ELFCLASS64.." on startup.

The only diffenece here was I didn't have to do play musical directories for it to work. The below post was instrumental in helping me to get this fixed. Thanks to "lore_giver at lycos dot co dot uk"

Running Oracle 9i on a
Solaris 9 (64 bit) platform with a Sun Server E250:
Apache version 1.3.27
PHP version 4.3.1

I was first getting "...wrong ELF class: ELFCLASS64.."
while doing a ./configure with the --with-oci8 and --with-oracle parameters.

After some unsuccessfull searched I renamed the $ORACLE_HOME/lib to $ORACLE_HOME/lib.org and then renamed the

Thereafter it went passed this config, but now failed on
not being able to find a libwtc9.so file which was in the
$ORACLE_HOME/lib directory  (this message was displayed in the debug.log in the php source directory).

After setting the Environment variable:
I was able to compile without any errors and 'make' and 'make install' ran smoothly.

I only had to add the php type in the httpd.conf (in your apache conf directory eg. /usr/local/apache/conf)..
AddType application/x-httpd-php .php
to get the php to work again...

I had to then reverse the $ORACLE_HOME/lib swop on top since php was now having problems with the 32 bit version of the library...so switched it back to 64 and my php script worked....

Hope this helps some out there with similar problems..

Configuring/Compiling PHP as a DSO with Oracle support from source on a Sun Solaris 8 box.  We had already installed Oracle 9.2.0 client tools.

1. Make sure the following tools are installed

   They can be downloaded from http://www.sunfreeware.com.
2.  Make sure Apache is installed with DSO support.  We ran the Apache configure/compile like so:

   LIBS=-lpthread ./configure \
   --prefix=/usr/local/apache \
   --enable-module=most \
   make install
3.  If you haven't already, install the Oracle client tools.
4.  Make sure the following environment variables are set correctly and are accessible by all users.  We set them in /etc/profile.

   (technically, only $ORACLE_HOME is required, but you'll want to set the rest in order to make sure things run smoothly afterward)
5.  Make sure '/usr/ccs/bin' is in your path.  If not, add it.
6.  Unpack PHP source (php-4.2.3):

   gunzip php-4.2.3.tar.gz
   tar xvf php-4.2.3.tar
   cd php-4.2.3

7.  Run PHP configure like so :

   CC=gcc ./configure --with-apxs=/usr/local/apache/bin/apxs \
   --with-config-file-path=/etc \
   --with-mysql \
   --enable-ftp \
   --with-oci8=/path/to/ORACLE_HOME \
   --with-oracle=/path/to/ORACLE_HOME \
8.  Run make:  make
9.  Run this as root:  make install
10.  Change the LoadModule line in httpd.conf to include the fully qualified path.  For us:

   LoadModule php4_module        /usr/local/apache/libexec/libphp4.so
11.  Make sure the PHP files types are recognized in your httpd.conf file:

   AddType application/x-httpd-php .php
   AddType application/x-httpd-php-source .phps
12.  Test the configuration:

   /usr/local/apache/bin/apachectl configtest
   It should return "Syntax OK"
13.  Bounce Apache:

   /usr/local/apache/bin/apachectl restart
14.  Here's a simple PHP script to test the setup.  If you don't have access to the default tables Oracle provides, change the connections/tablenames/fields to match your setup:


= ocilogon("scott", "tiger");

$cmdstr = "select ename, sal from emp";
$parsed = ociparse($db_conn, $cmdstr);
$nrows = ocifetchstatement($parsed, $results);
"Found: $nrows results<br><br>\n";

"<table border=1 cellspacing='0' width='50%'>\n";

   for (
$i = 0; $i < $nrows; $i++ ) {
"<td>" . $results["ENAME"][$i] . "</td>";
"<td>$ " . number_format($results["SAL"][$i], 2). "</td>";

Re: ora-12154 errors with PHP 4.2.3, Apache 1.3.27, and Oracle 9i (client only) I had two identical set ups, one on SuSE 8.0 and one on RedHat 8.0, the SuSE worked and RedHat errored with ora-12154! For some reason, having the apache user in the oracle group worked for SuSE but did not for RedHat, I had to run the Apache service as oracle user (the one used to install oracle client). Just wanted to share this little tidbit with anyone who might be pulling their hair out like me :-). Other key things were setting the ORACLE_HOME env variable before starting Apache (I did this in the profile file).

keywords: NLS_LANG, NLS_CHARACTERSET,SetEnv,putenv()

If you have tried setting the environment variables -- especially NLS_LANG -- in PHP with putenv(), and perhaps also in Apache with SetEnv, and you are still having trouble with PHP+Oracle and foriegn character sets (you get e.g. 'd' for ''), try setting the environment variables in your PROFILE (e.g. under bash) BEFORE starting the Apache server once more. This finally stopped the problems we were having. For reference, set the following variables:


An example would be:


Then restart Apache (see below for important note).

Our system was Sun SPARC 5.8, running Apache 1.3.26 with PHP 4.2.2, and the OCI8 API for Oracle.

One further note: restart Apache with:

  apachectl stop
  apachectl start

rather than

  apachectl restart

otherwise your environment may not be reset.

Hope this helps someone!

If you still have ORA-12154 failed with Apache PHP on oracle8i
1.edit httpd.conf the apache starter user should the same user(and group) who install oracle(oracle:oinstall)

2.make apache starter .bash_profile the same with user who install oracle
3.and restart apache and php
4.make sure
$c2 = ocilogon("scott","tiger",$db);

the $db should the same with /etc/oratab  SID

taht's all

I spent several hours tracking down error ORA 24374, which would result from only *SOME* of my select statements.  This error would be caused if I made a query that would return any non-numerical value.  I am running an Apache 1.3.x webserver and PHP 4.2.1.

The fix is to add entries in your httpd.conf file that would export your environment settings.  I added these three lines and everything worked like a charm!
SetEnv ORACLE_HOME  /path/to/oracle/home
SetEnv ORA_NLS33  /path/to/oracle/home/ocommon/nls/admin/data

Obviously, if your NLS_LANG is different, you should set it to whatever your NLS_LANG actually is.  Ask your friendly DB admin for this information.

Hope this helps someone who treads down the path that I just followed!

Sometimes Oracle doesn't cleanup shadow processes when accessed from PHP. To avoid that, check your
$ORACLE_HOME/network/admin/tnsnames.ora file in your Oracle Client directory and remove the (SERVER=DEDICATED) token if is set.

To let Oracle delete shadow process on timeouts, add the following line in your $ORACLE_HOME/network/admin/sqlnet.ora
found in your ORACLE Server directory:


Where 'n' is the number of minutes to let connection idle befor shutting them out.

Debian / Apache / PHP oci8 / Oracle

I just wanna tell my experience compiling the oci8 support from php debian sources. It gave me a lot of headache and I think it might be useful for others who use debian.

This is for debian woody (3.0), php 4.1.2, apache 1.3.24, oracle 8.1.7
(of course, it might be useful for other versions)

The Debian packages have not oci8 compiled in, so you must get the sources. Then I edited the debian/rules file and added the following:

on top:


to the COMMON_CONFIG variable:

to the modules variable, just bellow the above:
(like ... mhash, mysql, oci8, odbc ...)

The "shared" keyword was the key for me. Before using it I was getting "ld: cannot find -lclntsh" on the compile time.

This way the compiling with dpkg-buildpackage went fine. If oci8.so does not show up in the modules directory after install, look php-source-path/apache-build/ext/oci8/.libs - it's there.

If this still fails, look also to the oracle-stubs problem. Oracle is compiled against glibc 2.1 and woody comes with 2.2. But oracle gives some stubs libs for work-around the problem. I don't know if this is necessary for the client libs, but I suggest trying. Look at Oracle docs.

Now things goes terribly fine here.

Here's a little snipet that shows how to insert multiple clob fields. Worked for me.

$dbh = OCILogon($dst_user_name, $dst_password, $dst_db_name);

for($i = 0; $i < $src_rec_cnt; $i++) {
   $query = "insert into bid (id,time,resume,experience,comments) values ('$id[$i]','$time[$i]',empty_clob(),empty_clob(),empty_clob()) returning  resume,experience,comments into :resume,:experience,:comments";

   $stmt = OCIParse($dbh, $query);

   $clob1 = OCINewDescriptor($dbh, OCI_D_LOB);
   $clob2 = OCINewDescriptor($dbh, OCI_D_LOB);
   $clob3 = OCINewDescriptor($dbh, OCI_D_LOB);
   OCIBindByName ($stmt, ":resume", &$clob1, -1, OCI_B_CLOB);
   OCIBindByName ($stmt, ":experience", &$clob2, -1, OCI_B_CLOB);
   OCIBindByName ($stmt, ":comments", &$clob3, -1, OCI_B_CLOB);

   OCIExecute($stmt, OCI_DEFAULT);
   @$clob1->save ($resume[$i]);
   @$clob2->save ($experience[$i]);
   @$clob3->save ($comments[$i]);

I had big problems to get an Oracle 7 server working with the OCI8 client and PHP under Linux, while connection to an Oracle 8 server worked great (In fact I got an ORA-01005 when connecting to Oracle 7). I see that more people have this problem, so here is the solution:

1. Make sure the NLS files are in your ORACLE_HOME subtree under $ORACLE_HOME/ocommon/nls/admin/data.

2. Make sure the ORA_NLS33 parameter is unset or alternatively pointing to the above directory ($ORACLE_HOME/ocommon/nls/admin/data).

3. Add "export ORACLE_HOME=/usr/local/oracle" (for example) to your apache startup script. This is important!! Adding this variabele in the httpd.conf OR in your PHP script will _NOT_ solve the problem: the directory has to be known before the Oracle library is loaded.

Thanks to Ron Reidy for helping to tackle this problem.

Using OCI8 it seems putenv() doesn't seem to work for oracle environment (at least with Linux/Apache) variables, but once you get connected try issuing the sql stament:
ALTER SESSION SET NLS_whatever = value;
Seems to overide any default NLS parameters.

if you feel like you have too many oracle statements clouding up your php, i came up with a function to open a connection (if necessary), parse your sql statement, and return the executed query.  after you call the function, you can do whatever needs to be done.  makes like so much simpler: (do whatever you want with the errors)

function execute_query($query, &$connected) {

   if(!$connected) {
       $connected = @OCIPLogon($ORACLE_USER, $ORACLE_PASS,  $ORACLE_SID);

       if($error = OCIError()) {
           die("<font color=red>ERROR!! Couldn't connect to server!</font>");

   $stmt = @OCIParse($connected, $query);
   if($error = OCIError($cn))    {
       die("<font color=red>ERROR!! Statement syntax error!</font>");

   if($error = OCIError($stmt)) {
       die("<font color=red>ERROR!! Could not execute statement!</font>");

   return $stmt;

If you are getting the nasty ORA-12154 errors, try adding your http daemon user (listed in you httpd.conf file as "User" & "Group") to the same group as the Oracle Owner user, then be sure that the ORACLE_HOME environment variable is set to the Oracle Home Path, when you start apache.

VERY IMPORTANT!  OCIPLogon only keeps a persistent connection if you are running PHP as a module.  This is particularly important to Windows users who are used to running PHP as a CGI.

When using PHP4 in CGI-mode with Windows NT or Windows 2000 with IIS or Apache, make sure that the TNSNAMES.ORA and the SQLNET.ORA do not contain DOS/Windows CR/LF line endings.<br> Instead, they must have UNIX (only LF) endings. Otherwise, you will get an ORA-12154 error (TNS cannot resolve service name) when connecting to a remote database.<br>
This all does not matter if you use the ISAPI mode.

Here's a clue about rowid.

Don't forget about the oracle functions:

"rowidtochar" and "chartorowid"

"select rowidtochar(rowid) as FOO from table ...."

When you want to pass the rowid in a form or link, that's
the only way to go.

couple of notes about startup/shutdown on linux:  (redhat, maybe others)

export LD_PRELOAD=/usr/lib/libpthread.so

Caused the start/stop script to fail to stop the httpd process. 
The LD_PRELOAD environment var caused the 'ps' command to core dump.  I went bald figuring that out.

Easiest fix I could think of was to move all the oracle/php varialble exports so they are only set in the start section of the httpd script.

Never thought setting those vars globally in the script would cause problems.  That's what I get for thinking...

One other note:  Make sure the httpd process is shutdown before Oracle.


Lingering connections to oracle may cause shutdown to take forever.

If you're using OCI calls from apache/mod_php, and getting ORA-12514 errors, it's important to make sure your ORACLE_HOME environment variable is defined when you start apache.  If you use /etc/rc.d/init.d/httpd to start apache, simply put the environment variable definition in there.

This ORA-12514 error is baffling, because there isn't any such error code.  It actually should be ORA-12154 (but there's an error-code transposition somewhere in Oracle, on Linux).
