Inability to Connect to MySQL Database Using PHP

[Hagaroo]

I'm just learning PHP and MySQL, so please bear with me! I'm trying to connect to a MySQL database (v4.1.7) utilizing PHP (v4.3.9) but am having no luck. I'm able to run regular PHP scripts, so the PHP is set up correctly. I'm able to access the database using MySQL Administrator, so the database server is functional. Any time I try and connect utilizing a PHP script though, it fails. This same script functions at work, so I know it's not the script itself. Is there something obvious I'm missing or doing wrong. Any assistance would be greatly appreciated. Thanks!

what was your code in connecting ???

this should work pretty enough
$user='youruser';
$pass='yourpass';
$localhost='yourlocalhost';
$db='yourdatabase';
mysql_connect($localhost,$user,$pass) or die ("no connection :".mysql_error());
mysql_select_db($db) or die(mysql_error());
