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.

It is better to use this instead:
I read this somewhere on php.net.

wow... I am amazed, i never thought it could be this easy to block people from entering my website. just 3 or 4 lines of code: I am impressed. thanks.

I agree to flipper you should use $_SERVER['REMOTE_ADDR'] instead of get env
as using super global arrays are easy to use and are more powerful and it is also
a recommendation from php in its manual

Yeah php is pretty good but i prefer java

Could be really uesful, possible to add more IP's?

$blocked = "****.****.****.****, ****.****.****.****";

Or will you get an error ?

You'd have to define an array for that, and do a while loop to check if the IP is banned.

So that wont work then? :O

Sure it'll work, it'll just be more complex...
