PHP, the powerful and popular server-side scripting language for creating Web content, has become an important platform for Informix development.
Informix supports database access for client applications written in the PHP programming language by using a PDO (PHP Data Object) extension that functions as a database extraction layer. The primary PHP driver available for Informix is called PDO_IBM, and is supported on Informix Version 11.10, or later. You will find the drivers for PHP on the PECL for PHP web site (link resides outside of ibm.com). Users of Informix 11 or earlier can download the drivers here (link resides outside of ibm.com).
