PHP help accessing mySQL

I am having trouble accessing my database through PHP. I am running on Windows 200 with Apache 2.0.54, PHP 5.0.4 and mySQL 4.1.


When I enter the code:

<?php
$username = $_POST['username'];
$password = $_POST['password'];

// Database Variables
$DBhost = "localhost";
$DBuser = "";
$DBpass = "password";
$DBname = "testDB";
$tableName = "user";


// Connect to database and select database $DBname.
mysql_connect($DBhost,$DBuser,$DBpass)
or die("Unable to connect to database");
mysql_select_db("$DBname")
or die("Unable to select database $DBname");

echo("connected to $DBname");
?>


I get the following errors

Fatal error: Call to undefined function mysql_connect() in C:serverApache2htdocsWebsitevalidate.php on line 65



I was told to uncomment the ;extension=php_mysql.dll in the php.ini file. What I did was found all the php.ini files located in winnt and windows folder and uncommented it as well as line
include_path = ".;C:serverPHPext"
in the paths and directories section to point to my php_mysql.dll file. But when I run php I still get the same errors. Anybody know why.


Cheers and sorry for long read
