PHP 5.2.2 - Undefined Function mysql_connect()

["Jason Paschal" <jpaschal@xxxxxxxxx>]

I use this setup locally for testing/playing.  I recently installed the
latest and greatest of the AMP collection.

Apache 2.2.4
PHP 5.2.2
MySQL 5.0.37

Apache and PHP work fine together, but I wanted to hook it up to a local
test database, so  I installed MySQL.

In php.ini, i have:

; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:\PHP"

i made sure that i moved the dll to that folder, just like i did with the gd
dll.

And then i uncommented this line:

extension=php_mysql.dll

I restarted Apache, and ran a simple test script:

<?php
ini_set("display_errors","1");
$cn = mysql_connect("localhost","root","password");
?>

and I get the error:

*Fatal error*: Call to undefined function mysql_connect()

any ideas?

thanks in advance,
jason
