ThinkPHP is an open source PHP framework that has been widely used and supported. During the development process, it is often necessary to batch modify certain fields in the database. This article will introduce how to use the ThinkPHP5 framework to perform batch modification operations.

1. Preparation

First, make sure you have correctly installed PHP and ThinkPHP5 framework and connected to the database.

2. Create a controller

Use the ThinkPHP5 command line tool to create a controller and name it BatchController.

php?think?make:controller?BatchController

3. Create model

Use the ThinkPHP5 command line tool to create a model and name it BatchModel.

php?think?make:model?BatchModel

4. Write controller code

Add the following code in the BatchController class:

namespace?app\index\controller;
use?app\index\model\BatchModel;
class?BatchController
{
????public?function?index()
????{
????????$batch?=?new?BatchModel();
????????$result?=?$batch->batchUpdate();
????????return?'批量修改結(jié)果：'?.?$result;
????}
}

5. Write model code

Add the following code to the BatchModel class:

namespace?app\index\model;
use?think\Model;
class?BatchModel?extends?Model
{
????public?function?batchUpdate()
????{
????????$data?=?[
????????????['id'=>1,?'name'=>'張三'],
????????????['id'=>2,?'name'=>'李四'],
????????????['id'=>3,?'name'=>'王五'],
????????];
????????return?$this->saveAll($data);
????}
}

6. Test

Enter the following command on the command line to start the local server and access the index method of the BatchController controller.

php?think?run

Accessing http://localhost:8080/index/batch/index will batch modify the data in the data table.

7. Summary

In a few simple steps, we use ThinkPHP5 to perform batch modification operations. Finally, we remind you to perform necessary backup work before operating in the production environment to avoid data loss or damage.

ThinkPHP5 framework provides a wealth of development tools and documents, allowing developers to complete development tasks more efficiently and simply.
