php使用event扩展的io复用测试的示例

先要安装event扩展,这样才可以使用libevent的事件机制

pecl install event

测试代码

//连接重用//创建资源流的上下文$context=stream_context_create([\'socket\'=>[\'backlog\'=>2000]]);stream_context_set_option($context,\'socket\',\'so_reuseaddr\',1); //设置连接重用//sock_set_option($this->server, SOL_SOCKET, SO_REUSEADDR, 1); //复用还处于 TIME_WAIT$socket = stream_socket_server(\"tcp://0.0.0.0:8070\", $errno, $errstr,STREAM_SERVER_BIND | STREAM_SERVER_LISTEN,$context);stream_set_blocking($socket,false);//非阻塞//绑定事件$base=new EventBase();//监听服务端的socket$event=new Event($base,$socket,Event::PERSIST |Event::READ | Event::WRITE,function ($socket)use(&$base){$client = stream_socket_accept($socket);//stream_set_blocking($client,false);//非阻塞//    var_dump($client);//    $content=\'21335435\';//    $string=\"HTTP/1.1 200 OK\\r\\n\";//    $string.=\"Content-Type: text/html;charset=utf-8\\r\\n\";//    $string.=\"Content-Length: \".strlen($content).\"\\r\\n\\r\\n\";//    fwrite($client,$string.$content);//    fclose($client);//global $base;//var_dump($socket,$client);$base=new EventBase();//监听客户端socket$event=new Event($base,$client,Event::PERSIST |Event::READ | Event::WRITE,function ($client){$msg=fread($client,65535);////     if($msg){ //匹配请求头包含了keep-alive////     }$content=\'hello world\';$string=\"HTTP/1.1 200 OK\\r\\n\";$string.=\"Content-Type: text/html;charset=utf-8\\r\\n\";$string.=\"Connection: keep-alive\\r\\n\";$string.=\"Content-Length: \".strlen($content).\"\\r\\n\\r\\n\";fwrite($client,$string.$content);fclose($client);//当socket断开连接，删除事件$event->del();//删除事件});$event->add(); //加入事件监听$base->loop();//监视客户端//$event->del();//删除事件});$event->add(); //加入事件监听var_dump($base->loop()); //调度挂起事件监听
