You don't have to use fopen() when using readfile();

Just include the filename inside readfile() like this:

readfile($_GET['fileUrl']);

Although this is very dangerous security-wise as the user could specify any file on your file server. If you only have a few files you want someone to be able to download perhaps you should store them in an array (or database, preferebly)

Here's an array example:

$files = array('file1.jpg', 'file2.png', 'file3.pdf');
//assume $_GET['file_id'] == 0, 1 or 2

if (file_exists($files[$_GET['file_id']]))
    readfile($files[$_GET['file_id']]);
