(PHP) Ban Ip From Your Site

[Romance Of Love]

It is one of the effective code for banning the IP address from your website.
Just paste the codeinto your PHP page.

<?php 
// This will retrieve ip! 
$ip = getenv('REMOTE_ADDR'); 
// Replace 'x' with ip address! 
$blocked = "xx.xx.xx.xx"; 

if (ereg($blocked,$ip)) 
{ 
echo "You Have Been Banned"; 
exit(); 
} 
?> 
'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.

nice tutorial

may I share http://www.thewebmasterstool.com/tu...dy-who-has-done-something-wrong-on-your-site/ which is slightly more advanced as it uses MySQL but does the same job

You may also want to use array() funtion in your code to use more then one ip address.

 

[Daniel]

$ips = array("1.2.3.4", "2.3.4.5");

if(in_array($_SERVER['REMOTE_ADDR'],$ips)) 
{
	header("HTTP/1.0 403 Forbidden");
	die("Your IP has been banned.");
}

Untested...

you should also check $_SERVER['X_FORWARDED_FOR'] in case they are using a proxy (although some proxies hide both)

Enter the IP into 'hosts.deny'?
