###代码大概像这样吧，手打的，没有测试###

<code>php</code><code>$sql = 'INSERT INTO TABLE (`u_uid`, `userid`,`status`,`confirm_time`,`pv_total`) VALUES';
foreach($arr as $k => $item) {
    $sql .= '(' . $item['u_uid'] . ',' . $item['userid'] . ',' . $item['status'] . ',' . $item['confirm_time'] . ',' . $item['pv_total'] . '),';
}
$sql = rtrim($sql, ',');
</code>
Copy after login

对，就是这样的。

<code>sql</code><code>INSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....),(值1, 值2,....),(值1, 值2,....)
</code>
Copy after login

其实编程这玩意儿，你试试看就知道可不可行了。
