CXIV. PostScript document creation


This module allows to create PostScript documents. It has many similarities with the pdf extension. Actually the API is almost identical and one can in many cases just replace the prefix of each function from pdf_ to ps_. This also works for functions which has no meaning in the PostScript document (like adding hyperlinks) but will have an effect if the document is converted to PDF.

Documents created by this extension are sometimes even superior to documents created with the pdf extension, because pslib's text rendering functions can handle kerning, hyphenation and ligatures which results in much better output of boxed text.


You need at least PHP 4.3.0 and pslib >= 0.1.12. The ps library (pslib) is available at


A short installation note: just type
$ pear install ps
in your console.


本扩展模块在 php.ini 中未定义任何配置选项。


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。

The following two tables lists all constants defined by the ps extension.

I also was not able to install ps using PEAR. Here are the steps I took to getting it installed:

1. you may need to install the perl module XML::Parser ( to get pslib to install
2. install pslib (
3. install ps ( using the instructions from (
4. copy the file created by to the php extensions directory (not automatically done)
5. edit php.ini to include the ps extension (not automatically done)

If you are running FreeBSD, this link may help you with problems installing pslib (

Note that pslib (the library) and ps (the php extension) are not the same.

OK, OK, the previous note helped get me started, but really, it took me most of the day to figure out how to get this "pear install ps" to work. At first, it seemed geared for PHP4. Hopefully, I can save someone the day I just spent. (Don't get me wrong, I learned something new).

If the above statement doesn't work try this because it worked for me using PHP5 and Apache.

1. Forget the "pear install ps", it doesn't work. Whoever wrote that should get punched.
2. Make sure you've got PHP5 and Apache working as you like.
3. Go to and download the latest release.
4. Decompress the contents into its own directory somewhere.
5. Read which tells you what to do with what you just decompressed.
6. Move the final result (a shared object file) into the directory specified by your php.ini file's "extension_dir".
7. Create an entry in you php.ini (along with other similar statements that should already be there) that says ""
8. For giggles, restart apache

Worked for me, hope it works for you...

For everybody who is frustrated by the not working of 'pear install ps' command under most likely SuSE, at is a possible way to get it working. It is also possible to use these instructions under other distributions.
If 'pear install ps' works fine from the start (pslib etc is installed), but ps does not work yet, use dl(''); This will save you a lot of time.
