Find your user's their IP address:

Show your user's their IP address:

Retrieving the user's IP address is actually much simpler than you might think, and can be done in a single line. Getenv("REMOTE_ADDR") will return the IP address of the person visiting your site. Generally this is accurate, however if the user is running through a proxie server, then it will return the address of the proxie.
In this example, we retrieve the user's IP and then simply echo it's value back to the user.

<?php
 //Gets the IP address
 $ip = getenv("REMOTE_ADDR") ;
 Echo "Your IP is " . $ip;
 ?>
