<?php
    $hostname='localhost'; //// specify host
    $user='root'; //// database user name
    $password='root'; //// database password
    $database='test'; //// database name
    $connection = mysql_connect("$hostname" , "$user" , "$passwprd")
    or die ("Unable connect to MySQL");
    $db = mysql_select_db($database , $connection) or die ("Can't find database.");
