Blocking an IP

Does anyone know of a good IP blocker in php that will block IP's from your site?

RE: Blocking an IP

why don't you use htaccess? i'm assuming you're already running apache due to the php you're asking for

RE: Blocking an IP

IIS has (crappy) PHP support too...

Anyway, this code should work (although .htaccess is a good alternative):

<?php
$ip = getenv("REMOTE_ADDR");
$proxy = getenv("HTTP_X_FORWARDED_FOR");
if ($proxy) { // HTTP proxy used
$pos = 0;
while (($pos < strlen($proxy)) && ($proxy{$pos} != ','))
$pos++;
$ip = substr($proxy,0,$pos);
}
if ($ip == "1.2.3.4")
die("Sorry, you are not cool enough to view this page.");
?>

Just change the IP address in red to the one you wish to block.

If you want to block more than one IP address, you can use || (or) in the IF condition. If you want to block lots of them, you should probably use a better method of matching... Like using an array or something. :-/

Or just use .htaccess. :refuck:

Anyway, you can place the code at the top of the page, or perhaps under the <BODY> tag.

RE: Blocking an IP

Couldn't a JavaScript code do the same if PHP is unsupported?

You need to make one... You can make several ones and put them in different directories. But I don't know much about .htaccess so I can't help you with that really.

Theoretically, it could do something of the sort, but it would be quite stupid to do it that way.

You'd have to print the IP address in the code somewhere, which again requires PHP (or other server-side script)... And the banned user could still read the source or simply disable JavaScript. It's stupid.

No, that simply acts as DNS cache which overrides DNS lookups on your computer. It can be abused to block access to certain domain names from your PC (by pointing them to localhost or something), but not actual IP addresses. You'd have to use a firewall to do that. :-/

RE: Blocking an IP

I use this

code:
<?php

function ip_check()
{
// Addresses to block.
$block_ip[] = '203.217.64.174';
// Check current IP.
if (in_array($_SERVER['REMOTE_ADDR'], $block_ip))
{
return false;
}
else
{
return true;
}
}
?>

Then in your index file or whatever put this include

code:
<?php include 'bannedip.php'; if (!ip_check())
{
header( "Location: http://ng.audiodragon.net/bannage.php");
}
?>

Change the header location bit to the redirect site, bannedip.php to the name of your script.

You can also just display text using the echo command..
