php中的continue用法

if (count($content_arr) > 0 ) { // 获取相应的goods数据
    $goodsdata = array();
    foreach ($content_arr as $k_goods => $v_goods) {
        foreach ($goodslist as $k_g_list => $v_g_list) {
            if ($v_g_list['goods_id'] == $v_goods) {
                $goodsdata[] = $v_g_list;
                continue 2; // 跳出两层，直接到达content_arr的foreach中,if也算一层
            }
        }
    }
}
