# LIX. IBM Functions (PDO_IBM)

# Einführung

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

# Installation

To build the PDO_IBM extension, the DB2 Client v9.1 or later must be installed on the same system as PHP. The DB2 Client can be downloaded from the IBM Application Development Site.

> Note: The DB2 Client v9.1 or later supports direct access to DB2 for Linux, UNIX, and Windows v8 and v9.1 servers.

> The DB2 Client v9.1 also supports access to DB2 UDB for i5 and DB2 UDB for z/OS servers using the separately purchased DB2 Connect product.

PDO_IBM is a PECL extension, so follow the instructions in Kapitel 7 to install the PDO_IBM extension. Issue the configure command to point to the location of your DB2 Client header files and libraries as follows:

    bash$ ./configure --with-pdo-ibm=/path/to/sqllib[,shared]

The configure command defaults to the value of the `DB2DIR` environment variable.
