PHP $_GET sample for a simple URL reversing

get_sample.php

<?php

//Saves $_GET['url'] parameter to var
$reverseURL = $_GET['url'];

//Logs the reverse URL to page
echo "Reverse URL => " . $reverseURL . "<br />";

//Reverts the $reverseURL string and saves it to var
$regularURL = strrev($reverseURL);

//Logs the regular (unreversed) URL to page
echo "Regular URL => " . $regularURL . "<br />";

//You can save this file and use the built-in PHP server to test it, if desired.
//Just access it from a web server passing your reverse URL as url GET parameter.
