It is one of the effective code for banning the IP address from your website.
Just paste the codeinto your PHP page.
[PHP]<?php
// This will retrieve ip!
$ip = getenv('REMOTE_ADDR');
// Replace 'x' with ip address!
$blocked = "****.****.****.****";
if (ereg($blocked,$ip))
{
echo "You Have Been Banned";
exit();
}
?> [/PHP]
'echo "You Have Been Banned";' <-- this is the message which will be displayed when the banned ip goes on the page.
Remember to swap the x's with the IP you wish to ban.
