Maybe you can pass the hex value of the url with bin2hex() and then in your controller you can decode it using pack()
this is for generating the url
Code:
<?php
$url = site_url('test/play/'.bin2hex('http://your-url'));
and then
Code:
<?php
class Test extends Controller {
function Test()
{
parent::Controller();
}
function index()
{
function play($url)
{
echo pack('H*',$url);
}
}
