Informix Functions (PDO_INFORMIX)

Introduction

PDO_INFORMIX is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to Informix databases.

Installation

To build the PDO_INFORMIX extension, the Informix Client SDK 2.81 UC1 or higher must be installed on the same system as PHP. The Informix Client SDK is available from the » IBM Informix Support Site.

PDO_INFORMIX is a » PECL extension, so follow the instructions in Installation of PECL extensions to install the PDO_INFORMIX extension. Issue the configure command to point to the location of your Informix Client SDK header files and libraries as follows: 

   bash$ ./configure --with-pdo-informix=/path/to/SDK[,shared]
The configure command defaults to the value of the INFORMIXDIR environment variable.

Scrollable cursors

PDO_INFORMIX supports scrollable cursors; however, they are not enabled by default. To enable scrollable cursor support, you must either set ENABLESCROLLABLECURSORS=1 in the corresponding ODBC connection settings in odbc.ini or pass the EnableScrollableCursors=1 clause in the DSN connection string.
