    if (count($array) > 0) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                foreach ($v as $k2 => $v2) {
                    if ($k2 == $on) {

I see you found a solution but just in case I'll write my answer, maybe someone finds it useful

<?php
    $order_by = "asc";
    $list = array(
        array('type' => 'suite', 'name' => 'A-Name'),
        array('type' => 'suite', 'name' => 'C-Name'),
        array('type' => 'suite', 'name' => 'B-Name'),
    );
    usort($list, "customSort");

    function customSort($a, $b) {
        global $order_by;

        $compare = strcmp($a['name'], $b['name']);

        if($compare == 0) {
            return 0;
        } else if($compare > 0) {
            if($order_by == "asc") {
                return 1;
            } else {
                return -1;
            }
        } else if($compare < 0) {
            if($order_by == "asc") {
                return -1;
            } else {
                return 1;
            }
        }
    }

    echo "<pre>".print_r($list, true);
