Why would you do it if you hate it? :p
anyway I would connect to a database so you don't have to update the PHP file every so often. Also I would check for proxy servers as this is very easy to bypass this ban. I threw up a quick code below, so you can update it if you would like or just study.
<?php
//get ip or ip behind proxy
if($_SERVER["HTTP_X_FORWARDED_FOR"] != "")
{
$IP = $_SERVER["HTTP_X_FORWARDED_FOR"];
$proxy = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["HTTP_X_FORWARDED_FOR"]);
}
else
{
$IP = $_SERVER["REMOTE_ADDR"];
$proxy = "No proxy detected";
$host = @gethostbyaddr($_SERVER["REMOTE_ADDR"]);
}
//connect to database (mysql pref.)
//database connect here
$all_bans = mysql_query("SELECT * WHERE 'ban' = 'true'"); //get all ip bans
$banned = false; //initialize ban to false
//check through all the bans to determine if banned.
foreach( $banned_ip in $all_bans )
if($banned_ip == $IP)
$banned = true;
if($banned)
echo "Banned. gtfo.";
else
echo "Continue on! (Not Banned)";
?>

I just code some in php to learn a little bit just in case I need it in the future. :p
