Informix Functions (PDO_INFORMIX)

Introduzione

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

Installazione

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 the 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.

Informix PDO needs the INFORMIXDIR system variable available to the script running under the webserver, in my case apache 2.4.

Using setenv did not work, so I added in the systemd startup script /lib/systemd/system/apache2.service the following:

Environment=INFORMIXDIR=/opt/Informix_Software_Bundle

in the [Service] section.

Of course, the installation directory of your informix libraries may be different than /opt/Informix_Software_Bundle....
