PHP Tutorial : Block certain IP Address

I see this seems to be a very hot subject on the folks searching for php scripts and help. Its not really big deal to block a certain visitor IP Address. It works like : first you need to detect their IP, then you just send him a 404 not found header. Have a look:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$blocked = "127.0.0.1";

if($ip == $blocked) {
header("HTTP/1.0 404 Not Found");
exit();
}
?>
