一次性往mysql中插入10万条数据，只需7秒

$connect_mysql->autocommit(false);
    mysqli_query($connect_mysql,'set names utf8');
    $begin = time();
    $sqls ='';
    for($i=1;$i<=100000;$i++){
        $sqls .= "('....','.....','.....'),";
        if($i%10000=='0'){
            $sql = 'INSERT INTO `table` (`field1`,`field2`,`field3`) value'.rtrim($sqls, ",");
            mysqli_query($connect_mysql,$sql);
            $sqls ='';
            unset($sql);
