function array_sort($array, $on, $order=SORT_ASC){

    $new_array = array();
    $sortable_array = array();

    if (count($array) > 0) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                foreach ($v as $k2 => $v2) {
                    if ($k2 == $on) {
                        $sortable_array[$k] = $v2;
                    }
                }
            } else {
                $sortable_array[$k] = $v;
            }
        }

        switch ($order) {
            case SORT_ASC:
                asort($sortable_array);
                break;
            case SORT_DESC:
                arsort($sortable_array);
                break;
        }

        foreach ($sortable_array as $k => $v) {
            $new_array[$k] = $array[$k];

    return $new_array;
}

How to use

 $list = array(
   array( 'type' => 'suite', 'name'=>'A-Name'),
   array( 'type' => 'suite', 'name'=>'C-Name'),
   array( 'type' => 'suite', 'name'=>'B-Name')
 );

$list = array_sort($list, 'name', SORT_ASC);

array(3) { [0]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "A-Name"    } [2]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "B-Name" } [1]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "C-Name" } }
