In the world of industry database management, there are three major players: IBM DB2, Microsoft SQL Server and Oracle. There is a lot of literature about using both Microsoft and Oracle's products, but information on using DB2 specifically with PHP was difficult to find. I developed this tutorial to help the age PHP-MySQL application developer expand his or database horizons to include IBM's powerful database offering.

In PHP Database Programming with DB2 from SitePoint this morning, the author walks you through the setup and usage of a DB2 (IBM DB2 UDB) connection from PHP and how to abuse it for your own data needs.

This kind of connection is made on Windows with the help of an ODBC driver, and extended with a database class that they provide you with. These two put together make for a good, solid foundation to create the rest of a DB2 application on.
