Comparing IP addresses

Answer 1

You really want to do this completely on the server. If you check for IPs on the client side then people can very easily hack around that. For example by modifying your code in their browser using a web inspector like Firebug.

Fortunately it is pretty simple to do on the server side:

The $_SERVER['REMOTE_ADDR'] variable is a simple string so you should be able to use string comparison to check for the IPs that you want.

Like for example:

<?php
   if ($_SERVER['REMOTE_ADDR'] == "127.0.0.1" || $_SERVER['REMOTE_ADDR'] == "1.2.3.4") {
       echo "Show secret things here";
   }
?>
