### Plain PHP: ###

foreach($files as $file) {
    $currentSize = filesize($file);
    $data[] = array("name" => $file, "size" => $currentSize);
}

uasort($data, function($a, $b) {

   $bs = $b['size'];
   if($as == $bs) { return 0; }
   else return $as < $bs ? 1 : -1;
});

foreach($data as $x)
{
    echo $x['name'] . " " . $x['size'] . "<br>";
}

### Linq: ###

echo "<br/><br> Linq: <br /><br>";

$linq = Linq::from($files)
    ->select(function($x) { return array("name" => $x, "size" => filesize($x)); })
    ->orderByDescending(function($x) { return $x['size']; })
    ->each(function($x) {
        echo $x['name'] . " " . $x['size'] . "<br>";
    });
