Windows上的DB2和PHP(2003)

I'm using Apache 2.2 and PHP 5.2 on Windows Server 2003.

I need to comunicate with a DB2 IBM database via php.

The problem is that i've downloaded the PECL to DB2 IBM and pasted the file php_ibm_db2.dll on php/ext folder. Then i've inserted on php.ini the extension ( extension=php_ibm_db2.dll ). The apache is running php well, at least in can run pages with curl functions. But my php info() doesn't show the extension for DB, and can't recognize db2_connect() function.

Yes i've already restarted apache.

What I'm missing?

To comunicate with a DB2 external database (not in that computer), do I need to install any IBM software?
