Edit Problem Solved Thanks to Holix on IRC
Solved:

  function cmp($a, $b) {
    global $CFG_sorting_order, $CFG_sorting_type;
    if ($CFG_sorting_order == "ascending")
        {
                return strcasecmp($b['name'], $a['name']);
        }
    if ($CFG_sorting_order == "descending")
        {
                return strcasecmp($a['name'], $b['name']);
        }
	if ($CFG_sorting_order == "random")
        {
                return (mt_rand(0, 1) ? $a['name'] : $b['name']);
        }
  }
  @usort($dirs_raw,  'cmp');
  @usort($files_raw, 'cmp');

So heres my situation, my wallpapers site currently only supports sorting with ascending or descending. I would like my site to show the images randomly.

I've tried using shuffle() but I can't seem to get it to work.

Here is what I have:

  function cmp($a, $b) {
    global $CFG_sorting_order, $CFG_sorting_type;
    if ($CFG_sorting_order == "ascending")
        {
                return strcasecmp($b['name'], $a['name']);
        }
    if ($CFG_sorting_order == "descending")
        {
                return strcasecmp($a['name'], $b['name']);
        }
	if ($CFG_sorting_order == "random")
        {
                return shuffle($a['name'], $b['name']);
        }
  }
  @usort($dirs_raw,  'cmp');
  @usort($files_raw, 'cmp');

Here is the original:

  function cmp($a, $b) {
    global $CFG_sorting_order, $CFG_sorting_type;
    if ($CFG_sorting_order == "ascending")
        {
                return strcasecmp($b['name'], $a['name']);
        }
    if ($CFG_sorting_order == "descending")
        {
                return strcasecmp($a['name'], $b['name']);
        }
  } // function cmp
  @usort($dirs_raw,  'cmp');
  @usort($files_raw, 'cmp');

Any help is greatly appreciated!

In shuffle you just pass one argument which is an array?

It's hard to guess whats the purpose of this program, but first try array_merge() and then shuffle()
