How to use ThinkORM to implement database data archiving and cleaning

Overview:
A large amount of data is stored in the database. Over time, old data may become no longer important, so it is necessary Archiving and cleaning. This article will introduce how to use the ThinkORM framework to implement database data archiving and cleaning operations.

ThinkORM is a lightweight ORM framework based on PHP language. It provides a convenient database operation interface, which can simplify the database operation process and improve development efficiency. Next we will use ThinkORM to implement data archiving and cleaning functions.

Step 1: Configure database connection
First, we need to set the database connection information in the ThinkORM configuration file. Open the config/database.php file, find the connections array, and add the following code to the array:

'demo' => [
    // 数据库类型
    'type'     => 'mysql',
    // 服务器地址
    'host'     => '127.0.0.1',
    // 数据库名
    'database' => 'demo',
    // 用户名
    'username' => 'root',
    // 密码
    'password' => '123456',
    // 端口
    'port'     => '3306',
    // 字符集
    'charset'  => 'utf8mb4',
    // 数据库表前缀
    'prefix'   => 'think_',
    // 其他配置项...
],

In the above code, we configured a database connection named demo, including database type, server address, Database name, user name, password and other information. You can configure it accordingly according to your actual situation.

Step 2: Create a data model
Next, we need to create a data model to correspond to the tables in the database. Suppose we want to archive and clean the order table named orders, we create an Order model in the model directory under the application directory:

<?php

namespace appmodel;

use thinkModel;

class Order extends Model
{
    protected $connection = 'demo';
    protected $table = 'orders';
}

In the above code, we inherit the Model class of ThinkORM and set Connection name and table name. Modify the connection name and table name according to the actual situation.

Step 3: Implement the data archiving function

use appmodelOrder;

// 获取需要归档的订单数据
$archiveOrders = Order::where('created_at', '<', '2021-01-01')->select();

// 归档数据
foreach ($archiveOrders as $order) {
    // 执行归档操作，这里可以根据实际需求进行相应操作，例如将数据插入到归档表中
    // ...
    
    // 删除原始订单数据
    $order->delete();
}

In the above code, we use the where method of the Order model to filter the order data that needs to be archived, and then obtain the data through the select method. Then, we can perform archiving operations on this data, such as inserting data into an archive table. Finally, use the delete method to delete the original order data.

Step 4: Implement the data cleaning function

use appmodelOrder;

// 获取需要清理的订单数据
$cleanupOrders = Order::where('created_at', '<', '2020-01-01')->select();

// 清理数据
foreach ($cleanupOrders as $order) {
    // 执行清理操作，这里可以根据实际需求进行相应操作，例如备份数据或者直接删除
    // ...
    
    // 删除原始订单数据
    $order->delete();
}

In the above code, we use the where method of the Order model to filter the order data that needs to be cleaned, and then obtain the data through the select method. Then, we can clean the data, such as backing up the data or deleting it directly. Finally, use the delete method to delete the original order data.

Step 5: Scheduled tasks

In order to automatically trigger data archiving and cleaning operations, we can use scheduled tasks to achieve this. In ThinkPHP, you can use crontab to set up scheduled tasks. Open the config/crontab.php file and add the following code to the file:

return [
    'archive_orders' => [
        'command' => 'php think archive:orders',
        'cron' => '0 0 * * *',
        'log' => true,
        'output' => '',
    ],
    'cleanup_orders' => [
        'command' => 'php think cleanup:orders',
        'cron' => '0 1 * * *',
        'log' => true,
        'output' => '',
    ],
];

In the above code, we define two scheduled tasks: archive_orders and cleanup_orders. The archive_orders task is executed at 00:00 every day, and the cleanup_orders task is executed at 01:00 every day. It can be adjusted accordingly according to actual needs.

Finally, we need to create two commands to handle these two scheduled tasks. Use the following command on the command line to create a command file:

php think make:command ArchiveOrders
php think make:command CleanupOrders

After executing the above command, two files, ArchiveOrders.php and CleanupOrders.php, will be generated in the appcommand directory. Open these two files and add the following code respectively:

ArchiveOrders.php:

<?php

namespace appcommand;

use appmodelOrder;
use thinkconsoleCommand;
use thinkconsoleInput;
use thinkconsoleOutput;

class ArchiveOrders extends Command
{
    protected function configure()
    {
        $this->setName('archive:orders')->setDescription('Archive orders');
    }

    protected function execute(Input $input, Output $output)
    {
        $archiveOrders = Order::where('created_at', '<', '2021-01-01')->select();
        
        foreach ($archiveOrders as $order) {
            // 执行归档操作
            // ...
            
            // 删除原始订单数据
            $order->delete();
        }
        
        $output->writeln('Archive orders successfully.');
    }
}

CleanupOrders.php:

<?php

namespace appcommand;

use appmodelOrder;
use thinkconsoleCommand;
use thinkconsoleInput;
use thinkconsoleOutput;

class CleanupOrders extends Command
{
    protected function configure()
    {
        $this->setName('cleanup:orders')->setDescription('Cleanup orders');
    }

    protected function execute(Input $input, Output $output)
    {
        $cleanupOrders = Order::where('created_at', '<', '2020-01-01')->select();
        
        foreach ($cleanupOrders as $order) {
            // 执行清理操作
            // ...
            
            // 删除原始订单数据
            $order->delete();
        }
        
        $output->writeln('Cleanup orders successfully.');
    }
}
