ibase_pconnect

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

ibase_pconnect --  Open a persistent connection to an InterBase database

Description

resource ibase_pconnect ( [string database [, string username [, string password [, string charset [, int buffers [, int dialect [, string role [, int sync]]]]]]]] )

ibase_pconnect() acts very much like ibase_connect() with two major differences. First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection. Second, the connection to the InterBase server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ibase_close() will not close links established by ibase_pconnect()). This type of link is therefore called 'persistent'.

注: buffers was added in PHP 4.0.0.

注: dialect was added in PHP 4.0.0. It is functional only with InterBase 6 and versions higher than that.

注: role was added in PHP 4.0.0. It is functional only with InterBase 5 and versions higher than that.

See also ibase_close() and ibase_connect() for the meaning of parameters passed to this function. They are exactly the same.

To make a connection to a firebird database with pconnect many people like to use the SYSDBA, or database owner.
example:
$dbConnection = ibase_pconnect('path to db','SYSDBA','masterkey');

The above is fine unless you want to login in various user that have different permissions. To use permission make roles in the database, either as the database creator (or SYSDBA) and grant the roles to the various users.

If you login with...
$dbConnection = ibase_pconnect('path to db', 'USERNAME', 'userpassword');
...interbase will default your user to the PUBLIC role, which is created when the database is create and usualy has select rights on tables only. To get the proper role you will need to use all the parameters, like this...
$user='USERNAME';
$password='userpassword';
$role='MANAGER_HR';
$dbConnection = ibase_pconnect('path to db', $user, $password, '', 0, 3, $role, 0);

BTW - The "path to db", is formed like this...
---------------------
'localhost:c:/firebird/test_db/test.fdb'
---------------------

reading the interbase material, it states 3 connection methods, PHP appears to have selected the tcp type for us. So you can use localhost, or I suspect(never tested this myself) a ip address.
