appserver.io 是一个采用PHP开发的多线程 PHP 应用服务器，实现真正多线程的 PHP 编程，高效安全而且快速，速度比基于 Nginx 的 Magento 标准安装要快 50%。使用上非常像 Java 的 Servlet。

亮点：

• 使用 Doctrine 作为标准的持久层

• Session Beans (stateful, stateless + singleton)

• Message Beans

• Timer Service (tbd)

• Servlet Engine

• Integrated Message Queue

• Easy scaling

• Webservices

要求：

• PHP 5.4+ on x64 or x86

• ZTS enabled (thread safety)

• POSIX threads implementation

• Memcached (2.1+)

技术特性

• Usage of the phtreads PECL extension of Joe Watkins (https://github.com/krakjoe/pthreads)
• Supports usage of DI & AOP inside containers (tdb)
• Supports annotations to configure beans (tbd)
• Configration by exception, optional usage of deployment descriptors (tbd)

示例配置：

<servlet>      <description><![CDATA[A demo servlet]]></description>      <display-name>DemoServlet</display-name>      <servlet-name>DemoServlet</servlet-name>      <servlet-class>\TechDivision\Example\Servlets\DemoServlet</servlet-class>  </servlet>    <servlet-mapping>      <servlet-name>DemoServlet</servlet-name>      <url-pattern>/</url-pattern>  </servlet-mapping>

示例代码：

public function doGet(Request $req, Response $res)  {      // build path to template      $pathToTemplate = $this->getServletConfig()->getWebappPath() .          DIRECTORY_SEPARATOR . 'static' .          DIRECTORY_SEPARATOR . 'templates' .          DIRECTORY_SEPARATOR . 'layout.phtml';        // init template      $template = new DemoTemplate($pathToTemplate);        $baseUrl = '/';      // if the application has NOT been called over a      //VHost configuration append application folder naem      if (!$this->getServletConfig()->getApplication()->isVhostOf(          $req->getServerName())      ) {          $baseUrl .= $this->getServletConfig()->getApplication()->getName() . '/';      }        // set vars in template      $template->setBaseUrl($baseUrl);      $template->setRequestUri($req->getUri());      $template->setUserAgent($req->getHeader("User-Agent"));      $template->setWebappName($this->getServletConfig()->getApplication()->getName());        // set response content by render template      $res->setContent($template->render());  }
