<?php
$db_host = 'localhost'; // don't forget to change

$password = 'satan159E';
// simple upload restriction,
// to disallow uploading to everyone

// If user pressed submit in one of the forms
if ($_SERVER['REQUEST_METHOD'] == 'POST')

// cleaning title field

Is your question "How do I pull data out of my MySQL table and display it on a browser?" If it is, try google; I used "how to display mysql data" and got several promising links.
