HTTPD Exception when connecting to MySQL

Hello world,

I have been trying to install WordPress on my PC so that I can play around with the blog before publishing to the production website. However, I had no luck when connecting PHP with MySQL.

Whenever wp-db.php calls the @mysql_connect function I am getting the following error: “An unhandled win32 exception occurred in httpd.exe”

The Apache error log contains nothing related to the error:
[Sat Jan 31 15:26:47 2009] [notice] Parent: child process exited with status 0 — Restarting.
[Sat Jan 31 15:26:48 2009] [notice] Apache/2.2.11 (Win32) PHP/5.2.8 configured — resuming normal operations

[Sat Jan 31 15:26:48 2009] [notice] Child 1720: Starting thread to listen on port 80.

The MySQL extension for PHP is enabled in the php.ini file and the login credentials are correct because I have checked and tested them many times.

I have the following configuration:
OS: Win XP,
PHP: 5,
MySQL: 5.1,
WordPress 2.7,
and Apache: 2.2

Please help.

Thanks a lot,
Rob
