HomeBackend DevelopmentPHP TutorialWorkerman -- 高性能的 PHP socket 框架



Workerman 是一个高性能的PHP socket 服务器框架,workerman基于PHP多进程以及libevent事件轮询库,PHP开发者只要实现一两个接口,便可以开发出自己的网络应用,例如Rpc服务、聊天室服务器、游戏服务器等。

Workerman 的目标是让PHP开发者更容易的开发出基于socket的高性能的应用服务,而不用去了解PHP socket以及PHP多进程细节。 workerman本身是一个PHP多进程服务器框架,具有PHP进程管理以及socket通信的模块,所以不依赖php-fpm、nginx或者apache等这些容器便可以独立运行。

特性

  • 使用PHP开发

  • 支持PHP多进程

  • 支持TCP/UDP

  • 接口上支持各种应用层协议

  • 支持libevent事件轮询库,支持高并发

  • 支持服务平滑重启

  • 支持PHP文件更新检测及自动加载

  • 支持PHP长连接

  • 支持以指定用户运行子进程

  • 支持telnet远程控制

  • 高性能

基于workerman已经有很多的网络应用程序,例例如 多人在线小蝌蚪游戏 、 PHP-Json-Rpc 、 PHP-Thrift-Rpc 、 PHP-WebSocket聊天室 、 PHP统计监控系统 等等。

示例代码:

<?phpuse Workerman\Worker;require_once './Workerman/Autoloader.php';// 创建一个Worker监听2346端口,使用websocket协议通讯$ws_worker = new Worker("websocket://0.0.0.0:2346");// 启动4个进程对外提供服务$ws_worker->count = 4;// 当收到客户端发来的数据后返回hello $data给客户端$ws_worker->onMessage = function($connection, $data){    // 向客户端发送hello $data    $connection->send('hello ' . $data);};// 运行Worker::runAll();

性能压力测试

测试环境:

系统:ubuntu 12.04 LTS 64位内存:8Gcpu:Intel&reg; Core™ i3-3220 CPU @ 3.30GHz &times; 4

业务逻辑:

hello world

结果:

短链接(每次请求完成后关闭链接,下次请求建立新的链接):条件: 压测脚本开500个线程,每个线程链接Workerman 10W次,每次链接发送1个请求结果: 吞吐量:3W/S , cpu:60% , 内存占用:4*8M = 32M
长链接(每次请求后不关闭链接,下次请求继续复用这个链接):条件: 压测脚本开1000个线程,每个线程链接Workerman 1次,每个链接发送10W请求结果: 吞吐量:13W/S , cpu:68% , 内存占用:4*8M = 32M
无流量抖动,无内存泄漏,性能非常强悍

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
