Please note that most of the PDF functions require a pdf object as its first parameter. Please see the examples below for more information.

Please see the Database installation options chapter for more information about configuring PHP with these databases.

蛁 These are only used at compile time. If you want to alter PHP's runtime configuration, please see the chapter on Configuration.

Not every PHP directive is documented below. For a list of all directives, please read your well commented php.ini file. You may want to view the latest php.ini here from CVS.

ע An alternative PHP module for PDF document creation based on FastIO's ClibPDF is available. Please see the ClibPDF section for details. Note that ClibPDF has a slightly different API than PDFlib.

When using these functions, it is important to remember that while many of them have identical names to their C counterparts, they often have different declarations. Please be sure to read the descriptions to avoid confusion.

蛁 In PHP 3, methods are not preserved when unserializing a serialized object. PHP 4 removes that limitation and restores both properties and methods. Please see the Serializing Objects section of Classes and Objects or more information.

PHP can be built to support a large number of web servers. Please see Server related options for a full list of server related configure options. The PHP CGI binaries are compatible with almost all webservers supporting the CGI standard.

With PHP you can also write client side GUI applications using the PHP GTK extension. This is a completely different approach than writing web pages, as you do not output any HTML, but manage windows and objects within them. For more information about PHP GTK, please visit the site dedicated to this extension. PHP GTK is not included in the official PHP distribution.

The documentation in this section is only meant to be an overview of the available functions in the PDFlib library and should not be considered an exhaustive reference. Please consult the documentation included in the source distribution of PDFlib for the full and detailed explanation of each function here. It provides a very good overview of what PDFlib is capable of doing and contains the most up to date documentation of all functions.

The default is to build PHP as a CGI program. This creates a commandline interpreter, which can be used for CGI processing, or for non web related PHP scripting. If you are running a web server PHP has module support for, you should generally go for that solution for performance reasons. However, the CGI version enables Apache users to run different PHP enabled pages under different user ids. Please make sure you read through the Security chapter if you are going to run PHP as a CGI.
