MySQL+PHP - Cannot execute mysql functions

[Fratyr Metus]

Hello, I'm using Apache 2.2, PHP 5.2.9 and MySQL 5.1.34, WinXP 32 SP3, No firewalls, everything configured OK.
Before this, I've used WAMP Server and got the same error.
when I try to output something in HTML, or PHP - Everything works FINE.


Trying to connect to mysql through command line - works fine.

When I use ANY mysql command in PHP, such as $db = mysql_connect("host", "user", "pass");
I get this error in FF3 (same in IE7):

Connection Interrupted

The connection to the server was reset while the page was loading.

The network link was interrupted while negotiating a connection. Please try again.

That is what apache log error says after i run any mysql command:

httpd.conf is configured to localhost, php is configured and set up to load mysql library, the libraries located in php dir, also placed them in system32, system.. Dunno why, I've heard it may help.

Dunno what else can I do.. I need help. I just want to set up a development server for me.. :[
