)；
$count = count($res);
     $sql = "insert into users(periods,uid,username,pv) VALUES ";
           foreach($res as $key=>$vo){
                if($key == $count-1){
                    $sql .= "(".$periods.",".$vo['u_id'].",'".$vo['userid']."',".$vo['pv_total'].")";
                }else{
                    $sql .= "(".$periods.",".$vo['u_id'].",'".$vo['userid']."',".$vo['pv_total']."),";
                }
            };
            M()->query($sql);

这样能行吗？没怎么用过批量操作数据库，请指导。

Answer 1

###代码大概像这样吧，手打的，没有测试###

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

Answer 2

对，就是这样的。

sqlINSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....),(值1, 值2,....),(值1, 值2,....)

其实编程这玩意儿，你试试看就知道可不可行了。
