PHP的多線程應用服務器：appserver

appserver.io 是一個采用PHP開發的多線程 PHP 應用服務器，實現真正多線程的 PHP 編程，高效安全而且快速，速度比基于 Nginx 的 Magento 標準安裝要快 50%。使用上非常像 Java 的 Servlet。

亮點：

• 使用 Doctrine 作為標準的持久層

• 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+)

技術特性

• 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>

示例代碼：

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());
}
