1. What it does
IP banning someone from your site will effectivly stop all access they have to your website. Make sure you ban wisely 
2. The Code
The code is fairly simple, we will set the $banned variable using an array. It is here were we will enter IP address we wish to ban. Then, using the global variable $REMOTE_ADDR to give us the user's IP address, we can check if it is in the $banned array. If not, we let them carry on. If it is found in the $banned array, using the die() fuction, we can remove all access to the site from that IP.
<?php
$banned = array("1.1.1.1", "2.2.2.2", "3.3.3.3");
(in_array("$REMOTE_ADDR", $banned_addresses)) {
die("You have been banned from this site");
}
?>
3. Adding the ban filter
Save the above into ban.php or similar, then include it on all the pages you want it to be effective on, using the include() fuction.
