PHP 二维按照某个字段对数组排序

function arraySort($arr, $keys, $type = 'asc') {//二维按照某个字段对数组排序
        
        $keysvalue = $new_array = array();
        foreach ($arr as $k => $v){
            $keysvalue[$k] = $v[$keys];
        }
        $type == 'asc' ? asort($keysvalue) : arsort($keysvalue);
        reset($keysvalue);
        foreach ($keysvalue as $k => $v) {
           $new_array[$k] = $arr[$k];
