The Informix driver for Informix (IDS) 7.x, SE 7.x, Universal
Server (IUS) 9.x and IDS 2000 is implemented in "ifx.ec" and
"php_informix.h" in the informix extension directory. IDS 7.x support
is fairly complete, with full support for BYTE and TEXT
columns. IUS 9.x support is partly finished: the new data types
are there, but SLOB and CLOB support is still under construction.
This extension has been moved to the
» PECL repository and is no longer bundled with
PHP as of PHP 5.2.1.
