PHP异步协程开发：加速数据同步与迁移的效率

<?php

use SwooleCoroutine;

// 创建MySQL连接池
$mysqlPool = new SwooleCoroutineConnectionPool(
    function () {
        $mysql = new SwooleCoroutineMySQL();
        $mysql->connect([
            'host' => '127.0.0.1',
            'user' => 'root',
            'password' => 'password',
            'database' => 'source_database',
        ]);

        return $mysql;
    },
    50
);

// 异步协程处理数据
Coroutineun(function () use ($mysqlPool) {
    // 从源数据库读取数据
    $sourceData = (yield $mysqlPool->get())->query("SELECT * FROM source_table");

    // 迁移数据到目标数据库
    (yield $mysqlPool->get())->query("START TRANSACTION");
    foreach ($sourceData as $row) {
        (yield $mysqlPool->get())->query("INSERT INTO target_table (id, name) VALUES ({$row['id']}, '{$row['name']}')");
    }
    (yield $mysqlPool->get())->query("COMMIT");

    // 释放连接
    foreach ($mysqlPool->getAll() as $mysql) {
        $mysql->close();
    }
});
