PHP使用swoole编写简单的echo服务器示例_php技巧_

serv = new swoole_server('0.0.0.0', 8888); //配置参数 $this->serv->set(array( 'worker_num' => 4, 'daemonize' => 0, )); //注册回调函数 $this->serv->on('start', array($this, 'start')); $this->serv->on('connect', array($this, 'connect')); $this->serv->on('receive', array($this, 'receive')); $this->serv->on('close', array($this, 'close')); //启动服务 $this->serv->start(); } public function start($serv) { echo "start \n"; } //有客户端连接时 public function connect($serv, $fd) { echo "connect \n"; $serv->send($fd, "hello \n"); } public function close($serv, $fd) { echo "close \n"; } public function receive($serv, $fd, $from_id, $data) { echo "get message {$fd} : {$data} \n"; //向客户端发送信息 $serv->send($fd, $data . "\n"); } } $serv = new EchoServer(); 

client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); $this->client->on('connect', array($this, 'connect')); $this->client->on('receive', array($this, 'receive')); $this->client->on('close', array($this, 'close')); $this->client->on('error', array($this, 'error')); //连接服务端 $this->client->connect('0.0.0.0', 8888); } public function connect($client) { echo "connect \n"; } public function receive($client, $data) { echo "server send: {$data}"; //向标准输出写入数据 fwrite(STDOUT, "请输入消息："); //获取标准输入数据 $msg = trim(fgets(STDIN)); //向服务端发送数据 $client->send($msg); } public function close($client) { echo "close \n"; } public function error($client) { echo "error \n"; } } $cli = new EchoClient();
