This is like THE simplest, easiest way to make a certain web page only viewable by certain IP[s].

<?php
/*****************************
* Fetch IP
* You can also use:
* $ip = $_SERVER["REMOTE_ADDR"];
* Instead of:
* $ip = getnv(”REMOTE_ADDR”);
******************************/

$ip = getenv(”REMOTE_ADDR”);

// Add authorised IPs here
// example: $myip[0] = “127.0.0.1″;

$myip[0] = “IP_HERE”;
$myip[1] = “IP_HERE”;

/************************************************
* If you want to add more IPs, just copy the $myip line
* and change the IP and [0] accordingly
* [0] = first IP, [1] = second, [2] = thrid, and so on.
*
* Also if you are going to add another IP, don’t forget to
* edit the if line, for example, if you added a third IP
*
* this:
* if ($ip == $myip[0] || $ip == $myip[1])
*
* should be:
* if ($ip == $myip[0] || $ip == $myip[1] || $ip == $myip[2])
**************************************************/

if ($ip == $myip[0] || $ip == $myip[1]) {
?>

Your Site Content

<?php
}
else {
echo “Your IP is not authorized to view this page”;
}
?>

Of course there are many other ways in doing this, like using array(”ip1″, “ip2″), but this is the easiest one to understand for people who don’t know much about PHP.

This can basically be used for paranoid security, htpasswd + that script will make your page very secure.

Enjoy.
