<?php
if(basename(__FILE__) == basename($_SERVER['PHP_SELF'])) send_404();
$dbHost = "localhost";        //Location Of Database usually its localhost
$dbUser = "xxxx";            //Database User Name
$dbPass = "xxxx";            //Database Password
$dbDatabase = "xxxx";       //Database Name
 
$db = mysql_connect($dbHost,$dbUser,$dbPass) or die ("Error connecting to database.");
mysql_select_db($dbDatabase,$db) or die ("Couldn't select the database.");
 
# This function will send an imitation 404 page if the user
# types in this files filename into the address bar.
# only files connecting with in the same directory as this
# file will be able to use it as well.
function send_404()
{
    header('HTTP/1.x 404 Not Found');
    print '<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'."n".
    '<html><head>'."n".
    '<title>404 Not Found</title>'."n".
    '</head><body>'."n".
    '<h1>Not Found</h1>'."n".
    '<p>The requested URL '.
    str_replace(strstr($_SERVER['REQUEST_URI'],'?'),'',$_SERVER['REQUEST_URI']).
    ' was not found on this server.</p>'."n".
    '</body></html>'."n";
    exit;
}
 
 
# In any file you want to connect to the database,# and in this case we will name this file db.php 
# just add this line of php code (without the pound sign):
# include"db.php";
 
# once 
 
?>
