[PHP]IP Allowing

[Snarf]

This is a simple code I made, it just checks if your IP is in the list of allowed IPs.

PHP Code:

<?
$allow[0]="0.0.0.0"; 
if (in_array($_SERVER['REMOTE_ADDR'],$allow)) 
{ 
echo "Welcome" ;
}
else echo "You are not authorized to view this page."
?>

Replace 0.0.0.0 with the allowed IP.

I was thinking the same thing >>

Oh. Well can you move it?

EDIT: Just realized you already moved /facepalm.

EDIT #2: If you want more allowed IPs, use this code:

PHP Code:

<? 
$allow[0]="0.0.0.0";  
$allow[1]="0.0.0.0";
$allow[2]="0.0.0.0";
$allow[3]="0.0.0.0";
if (in_array($_SERVER['REMOTE_ADDR'],$allow))  
{  
echo "Welcome" ; 
} 
else echo "You are not authorized to view this page." 
?>

Just edit that into your first post.

A much easier way is to have a file which will have all the allowed IPs in (one per line). Say, for example, that the file is called "ipsallowed.txt", the code would be rather easy:

PHP Code:

<?php
if (preg_match('/^'.preg_quote($_SERVER['REMOTE_ADDR']).'$/m', @file_get_contents('ipsallowed.txt')))
{
    echo 'Allowed';
}
else
{
    echo 'Not allowed';
}
?>

PHP Code:

if(in_array($ip,explode(",",$bannedIps))){ die("MOAR LIKE BANNED. AMIRIGHT?!");} 


$bannedIps is the string with IPs separated by a comma.
