Swoole and Workerman's optimization methods for data mirroring and data synchronization between PHP and MySQL

Swoole and Workerman's optimization method for data mirroring and data synchronization between PHP and MySQL

Overview:
In modern application development, data mirroring and Synchronization is crucial. Especially in the combination of PHP and MySQL, how to effectively perform data mirroring and data synchronization has become a key issue. This article will introduce how to use Swoole and Workerman to implement data mirroring and data synchronization between PHP and MySQL, and give specific code examples.

Introduction:
In traditional PHP applications, polling or timers are usually used for data mirroring and data synchronization. The problem with this method is that it is less efficient and takes up a lot of system resources. Swoole and Workerman are event-driven high-performance frameworks that can give full play to the advantages of PHP and MySQL and improve the efficiency of data mirroring and data synchronization.

1. Swoole implements data mirroring and data synchronization
Swoole is a high-performance network communication framework developed specifically for PHP. It improves the concurrency capabilities of PHP programs by using asynchronous and multi-threading methods. The following is a code example that uses Swoole to implement data mirroring and data synchronization:

require 'vendor/autoload.php';

use SwooleTimer;

// Configure source database
$srcHost = 'localhost';
$srcUser = 'root';
$srcPassword = '';
$srcDatabase = 'demo';
$ srcPort = 3306;

//Configure the target database
$dstHost = 'localhost';
$dstUser = 'root';
$dstPassword = '';
$dstDatabase = 'mirror_demo';
$dstPort = 3306;

//Connect to the source database
$srcDb = new mysqli($srcHost, $srcUser, $srcPassword, $srcDatabase, $srcPort);
if ($srcDb->connect_errno) {

die('Connect Error (' . $srcDb->connect_errno . ') ' . $srcDb->connect_error);

}

// Connect to the target database
$dstDb = new mysqli($dstHost, $dstUser, $dstPassword, $dstDatabase , $dstPort);
if ($dstDb->connect_errno) {

die('Connect Error (' . $dstDb->connect_errno . ') ' . $dstDb->connect_error);

}

// Timer, synchronize data every 10 seconds
Timer:: tick(10000, function() use ($srcDb, $dstDb) {

// 查询源数据库的数据
$result = $srcDb->query('SELECT * FROM table');

// 清空目标数据库的数据
$dstDb->query('TRUNCATE table');

// 遍历源数据库的数据，插入到目标数据库
while ($row = $result->fetch_assoc()) {
    $sql = "INSERT INTO table (col1, col2) VALUES ('" . $row['col1'] . "', '" . $row['col2'] . "')";
    $dstDb->query($sql);
}

});

// Start the Swoole event loop
swoole_event_wait();
?> ;

By using Swoole's timer, data can be read from the source database regularly and synchronized to the target database. In this way, the functions of data mirroring and data synchronization are realized.

2. Workerman implements data mirroring and data synchronization
Workerman is a multi-process, high-performance PHP network communication framework that improves the concurrency capabilities of PHP programs by using multiple processes. The following is a code example that uses Workerman to implement data mirroring and data synchronization:

require 'vendor/autoload.php';

use WorkermanWorker;

$worker = new Worker();

$worker->onWorkerStart = function($worker) {

// 配置源数据库
$srcHost = 'localhost';
$srcUser = 'root';
$srcPassword = '';
$srcDatabase = 'demo';
$srcPort = 3306;

// 配置目标数据库
$dstHost = 'localhost';
$dstUser = 'root';
$dstPassword = '';
$dstDatabase = 'mirror_demo';
$dstPort = 3306;

// 连接源数据库
$srcDb = new mysqli($srcHost, $srcUser, $srcPassword, $srcDatabase, $srcPort);
if ($srcDb->connect_errno) {
    die('Connect Error (' . $srcDb->connect_errno . ') ' . $srcDb->connect_error);
}

// 连接目标数据库
$dstDb = new mysqli($dstHost, $dstUser, $dstPassword, $dstDatabase, $dstPort);
if ($dstDb->connect_errno) {
    die('Connect Error (' . $dstDb->connect_errno . ') ' . $dstDb->connect_error);
}

// 定时器，每10秒钟同步一次数据
WorkermanLibTimer::add(10, function() use ($srcDb, $dstDb) {
    // 查询源数据库的数据
    $result = $srcDb->query('SELECT * FROM table');

    // 清空目标数据库的数据
    $dstDb->query('TRUNCATE table');

    // 遍历源数据库的数据，插入到目标数据库
    while ($row = $result->fetch_assoc()) {
        $sql = "INSERT INTO table (col1, col2) VALUES ('" . $row['col1'] . "', '" . $row['col2'] . "')";
        $dstDb->query($sql);
    }
});

};

Worker::runAll() ;
?>

By using Workerman's timer, data can be read from the source database regularly and synchronized to the target database. In this way, the functions of data mirroring and data synchronization are realized.

Conclusion:
This article introduces how to use Swoole and Workerman to optimize data mirroring and data synchronization between PHP and MySQL, and gives specific code examples. By using the high-performance features of Swoole and Workerman, the efficiency of data mirroring and data synchronization can be improved, and the data synchronization process between PHP and MySQL can be optimized. This is very important to improve the performance and stability of your application.
