General IP Banning

[wintallo]

Hey,

First, thanks for reading! Second, I'm looking for a PHP script that bans IP addresses that [u]don't[/u] have the first octet of 69. For example, the script would block the IP address 23.34.21.255, but it wouldn't block the ip address 69.93.147.82. I already know that to get the user's ip address you use the getenv("REMOTE_ADDR") command. I just don't know how to split the IP address up so the script can just test the first octet. Again, thanks for reading!

You can use the .htaccess file for that. I am not sure how to do it exactly, but I think you should put in the .htaccess

[code]deny from all
allow from 69.[/code]

I am not sure about the above tho!

Thanks for the reply, but I need a PHP script to do this.

Use the [url=http://www.php.net/explode]explode()[/url] function:
[code]<?php
$ip = '69.73.147.62';
$octets = explode('.',$ip);
echo 'The first octet is ' . $octets[0];
?>[/code]

[code]<?php
//$ip contains the user ip

$parts = explode(".", $ip);
if($parts[0] != 69)
die("Get lost, you're not a 69!");
else
{
//valid user
}

?>[/code]

Orio.

EDIT- ken is faster I guess ;)
