[Php] Encoding URL - Change encoding

[champ_rock]

Hi PHP Gurus

I need your help again!! please see http://pastebin.com/m20da3c65

I am trying to create a new encoding system for the URLs of my proxies. For this I need to edit proxifyURL() and deproxifyURL() functions which are given in the pastebin above.

I am looking to add some sort of a key mechanism where i can specify a key and change it daily so that my website remains unblocked.

Any kind of help / guidance/ tutorial / codes will be highly appreciated.

thanks

Lots of ways to do this, I'll just post one I have already written.

<?php

$string = 'http://google.com/search?q=Hello';

$key = (int) date("j");
/** This value can obviously be hard coded too, if you need it to be. */

function encode($string)
{
	global $key;
	$array = str_split($string);
	foreach($array as &$a)
	{
		$a = ord($a);
		$a = $a * $key;
	}
	$string = implode('_',$array);
	return $string;
}

function decode($string)
{
	global $key;
	$array = explode("_", $string);
	foreach($array as &$a)
	{
		$a = $a / $key;
		$a = chr($a);
	}
	$string = implode('', $array);
	return $string;
}

?>

i removed the base_64 encoding in the previous one and added urs but it is returning these strings 0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0_0 for whatever i input
