Swoole and Workerman's optimization method for data batch operations and batch operation submission in PHP and MySQL

Swoole and Workerman's optimization method for data batch operations and batch operation submission between PHP and MySQL

In PHP development, interaction with the database is a very common operation . However, when the amount of data is large, submitting a large amount of data to the database at one time may cause performance degradation. In order to solve this problem, we can use Swoole and Workerman to implement batch operations of data and optimization of batch operation submission.

1. Use of Swoole
Swoole is a high-performance PHP extension that can provide support for multi-process model and coroutine model for PHP. The following is a sample code for using Swoole for data batch operations and batch operation submission:

<?php
// 创建Swoole进程
$worker = new SwooleProcess(function () {
    // 连接到数据库
    $db = new mysqli('localhost', 'root', 'password', 'database');
    
    // 批量操作数据
    $sql = 'INSERT INTO `table` (`id`, `name`) VALUES ';
    for ($i = 0; $i < 10000; $i++) {
        $sql .= '(' . ($i + 1) . ', "name' . ($i + 1) . '"),';
    }
    $sql = rtrim($sql, ',');

    // 执行SQL语句
    $db->query($sql);
    
    // 关闭数据库连接
    $db->close();
});

// 启动Swoole进程
$worker->start();

In the above sample code, we created a Swoole process and used mysqli to connect to the database in the process, and then spliced Perform batch operations on data using SQL statements. After executing the SQL statement, we close the database connection.

2. The use of Workerman
Workerman is a memory-resident PHP high-performance framework that can handle long connections and a large number of concurrent requests. The following is a sample code for using Workerman for data batch operations and batch operation submission:

<?php
use WorkermanMySQLConnection;
use WorkermanWorker;

// 连接到数据库
$db = new Connection('host', 'port', 'user', 'password', 'database');

// 创建一个Worker监听端口
$worker = new Worker();

// 接收到数据后的回调函数
$worker->onMessage = function ($connection, $data) use ($db) {
    // 批量操作数据
    $sql = 'INSERT INTO `table` (`id`, `name`) VALUES ';
    for ($i = 0; $i < 10000; $i++) {
        $sql .= '(' . ($i + 1) . ', "name' . ($i + 1) . '"),';
    }
    $sql = rtrim($sql, ',');

    // 执行SQL语句
    $db->query($sql);
    
    // 返回结果
    $connection->send('Data inserted successfully');
};

// 运行Worker
Worker::runAll();

In the above sample code, we first use Workerman's MySQL connection class to connect to the database. Then create a Worker instance and process the received data through the onMessage callback function. In the callback function, we use the same method to perform batch operations and submission of data, and return the results through the send method.

3. Optimization of batch operations and submission
In the above example code, we used the method of splicing SQL statements to perform batch operations and submission of data. However, when the amount of data is very large, this approach may cause performance issues with string concatenation. To optimize batch operations and commits, we can use prepared statements and transactions to improve performance. The following is a sample code for batch data operation and submission using prepared statements and transactions:

<?php
// 连接到数据库
$db = new mysqli('localhost', 'root', 'password', 'database');

// 开启事务
$db->begin_transaction();

// 预处理SQL语句
$stmt = $db->prepare('INSERT INTO `table` (`id`, `name`) VALUES (?, ?)');

// 批量操作数据
for ($i = 0; $i < 10000; $i++) {
    $id = $i + 1;
    $name = 'name' . $id;
    $stmt->bind_param('is', $id, $name);
    $stmt->execute();
}

// 提交事务
$db->commit();

// 关闭数据库连接
$db->close();

In the above sample code, we first use mysqli to connect to the database and start the transaction through the begin_transaction method. Then use the prepare method to preprocess the SQL statement and bind parameters through bind_param to achieve the effect of batch operations. Finally, the transaction is submitted through the commit method to complete the batch operation and submission. After the code execution is completed, we close the database connection.

With optimized batch operations and submission methods, we can improve the performance of PHP and MySQL and be more efficient when processing large amounts of data. At the same time, using high-performance frameworks such as Swoole and Workerman can also greatly improve PHP's concurrency capabilities and further improve program performance.
