用于二维数组排序

function array_sort($arr, $field, $by = SORT_ASC)

{

    foreach ($arr as $v) {

        $r[] = $v[$field];

    }

    array_multisort($r, $by, $arr);

    return $arr;

}

 

function sort_array($array, $keyid, $order='asc', $type='number') {

    if(is_array($array)) {

        foreach($array as $val) {

            $order_arr[] = $val[$keyid];

        }

  

        $order = ($order == 'asc') ? SORT_ASC: SORT_DESC;

        $type  = ($type == 'number') ? SORT_NUMERIC: SORT_STRING;

  

        array_multisort($order_arr, $order, $type, $array);

    }

}
