Swoole和Workerman是PHP的两个高性能网络框架,它们在大数据量查询和传输方面都有一定的优化方法。本文将针对这两个框架,具体介绍它们在PHP与MySQL大数据量查询和传输方面的优化方法,并提供相应的代码示例。
一、Swoole对PHP与MySQL大数据量查询和传输的优化方法:
以下是使用Swoole协程进行MySQL查询的示例代码:
<?php Coun(function () { $db = new SwooleCoroutineMySQL(); $db->connect([ 'host' => '127.0.0.1', 'port' => 3306, 'user' => 'root', 'password' => '123456', 'database' => 'test', ]); // 开始协程 go(function () use ($db) { $result = $db->query('SELECT * FROM table'); var_dump($result); }); // 开始协程 go(function () use ($db) { $result = $db->query('SELECT * FROM table2'); var_dump($result); }); }); ?>
以下是使用Swoole连接池进行MySQL查询的示例代码:
<?php $dbPool = new SwooleCoroutineChannel(10); // 设置连接池大小为10 $dbConfig = [ 'host' => '127.0.0.1', 'port' => 3306, 'user' => 'root', 'password' => '123456', 'database' => 'test', ]; for ($i = 0; $i < 10; $i++) { go(function () use ($dbConfig, $dbPool) { $db = new SwooleCoroutineMySQL(); $db->connect($dbConfig); $dbPool->push($db); // 将连接放入连接池 }); } go(function () use ($dbPool) { $db = $dbPool->pop(); // 从连接池中取出一个连接 $result = $db->query('SELECT * FROM table'); var_dump($result); $dbPool->push($db); // 将连接放回连接池 }); ?>
二、Workerman对PHP与MySQL大数据量查询和传输的优化方法:
以下是使用Workerman多进程查询MySQL的示例代码:
<?php use WorkermanWorker; use WorkermanConnectionTcpConnection; $worker = new Worker(); $worker->count = 4; // 设置进程数为4 $worker->onWorkerStart = function ($worker) { $db = new mysqli('127.0.0.1', 'root', '123456', 'test'); if ($db->connect_errno) { printf("Connect failed: %s ", $db->connect_error); exit(); } // 每个进程中的回调函数单独查询数据 $worker->onMessage = function (TcpConnection $connection, $data) use ($db) { $result = $db->query('SELECT * FROM table'); $connection->send($result->fetch_all(MYSQLI_ASSOC)); }; }; Worker::runAll(); ?>
以下是使用Workerman缓存查询结果的示例代码(使用Redis作为缓存):
<?php use WorkermanWorker; use WorkermanConnectionTcpConnection; use WorkermanlibTimer; use PredisClient; $worker = new Worker(); $worker->count = 4; $redis = new Client(array( 'scheme' => 'tcp', 'host' => '127.0.0.1', 'port' => 6379, )); $worker->onWorkerStart = function ($worker) use ($redis) { // 查询数据并存入缓存 $current_time = time(); $result = $redis->get('data'); if (!$result) { $db = new mysqli('127.0.0.1', 'root', '123456', 'test'); if ($db->connect_errno) { printf("Connect failed: %s ", $db->connect_error); exit(); } $result = $db->query('SELECT * FROM table'); $redis->set('data', serialize($result)); $redis->expire('data', 60); // 设置缓存失效时间为60秒 $db->close(); } else { $result = unserialize($result); } // 每个进程中的回调函数返回缓存结果 $worker->onMessage = function (TcpConnection $connection, $data) use ($result) { $connection->send($result); }; }; // 定期更新缓存 $worker->onWorkerStart = function ($worker) use ($redis) { Timer::add(60, function () use ($redis, $worker) { $db = new mysqli('127.0.0.1', 'root', '123456', 'test'); if ($db->connect_errno) { printf("Connect failed: %s ", $db->connect_error); exit(); } $result = $db->query('SELECT * FROM table'); $redis->set('data', serialize($result)); $db->close(); // 更新每个进程中的结果 foreach ($worker->connections as $connection) { $connection->send($result); } }); }; Worker::runAll(); ?>
以上就是Swoole和Workerman对PHP与MySQL大数据量查询和传输的优化方法的详细介绍,以及相应的代码示例。通过使用Swoole的协程和连接池,以及Workerman的多进程和缓存,我们可以提高PHP与MySQL大数据量查询和传输的效率,提升系统性能。
