encoding url not working

[andy1212]

I'm trying to encode a url like this,

$code = '2';

header('Location: http://www.whatever.com/page.php?='.urlencode($code).'');
exit();

and then decoding it on the page.php page like this,

$url = $_SERVER['REQUEST_URI'];
$decodedurl = urldecode($url);

$code = $_GET[$decodedurl];

echo $code;

But when the header redirects to page.php, "2" doesn't get encoded, it just says "page.php?code=2"

 

How can I get this to work? Thanks for your time.

so in the url bar of the browser window it shows, http://www.whatever.com/page.php?code=2 but I thought it would show something like, page.php?code=%&2&%

The number 2 does not need to be encoded. Only special characters / high-order characters need to be encoded. Also there is no need to decode the URL. PHP does that automatically when it parses the variables out. So on your receiving page you'd just do $_GET['code'] like normal.
