Analysis of the maximum data amount supported by THINKPHP's addAll

This article mainly introduces the maximum amount of data supported by THINKPHP's addAll. Friends who need it can refer to it

There are two methods for Model operation in Thinkphp: add() and addAll

 $User = M("User"); // 实例化User对象
 $data['name'] = 'ThinkPHP';
 $data['email'] = 'ThinkPHP@gmail.com';
 $User->add($data);
 $dataList[] = array('name'=>'thinkphp','email'=>'thinkphp@gamil.com');
 $dataList[] = array('name'=>'onethink','email'=>'onethink@gamil.com');
 $User->addAll($dataList);

# The ##addAll method can add data in batches, which is how MySQL is used:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

When the amount of data is large, try to choose batch insertion instead of looping one by one, otherwise your database will be overwhelmed. Lose.

But if you take it for granted and store all the data into an array and perform addAll, you will also face a hang-up situation. Why is this?

The reason is that the configuration of the max_allowed_packet variable in mysql limits the length of the upload sql statement. Just configure it larger in the mysql configuration.

max_allowed_packet = 100M

At the same time, When inserting data, also limit the length of batch insertion. After all, you never know when the data will become millions.

The above is the entire content of this article. I hope it will be helpful to everyone's study. For more related content, please pay attention to the PHP Chinese website!
