...in particular, most easily done with usort() as described in a couple of answers there. –  Michael Berkowski Jan 21 '13 at 0:30

You can use usort() like this.

usort($torrentList, function($a, $b) {
    return $a['seed'] - $b['seed'];
});

Where $torrentList is the the array you showed us above. Documentation can be found here.

I'm surprised I wasn't the one who was beaten, happens to me more often than not. –  Austin Brunkhorst Jan 21 '13 at 0:37
