PHP使用swoole編寫簡單的echo服務器示例

?php
class EchoServer {
  protected $serv = null;
 
  public function __construct() {
    $this->serv = new swoole_server('0.0.0.0', 8888);
    //配置參數(shù)
    $this->serv->set(array(
      'worker_num' => 4,
      'daemonize' => 0,
    ));
    //注冊回調函數(shù)
    $this->serv->on('start', array($this, 'start'));
    $this->serv->on('connect', array($this, 'connect'));
    $this->serv->on('receive', array($this, 'receive'));
    $this->serv->on('close', array($this, 'close'));
    //啟動服務
    $this->serv->start();
  }
 
  public function start($serv) {
    echo "start \n";
  }
 
  //有客戶端連接時
  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";
    //向客戶端發(fā)送信息
    $serv->send($fd, $data . "\n");
  }
}
 
$serv = new EchoServer();

?php
class EchoClient {
  protected $client = null;
 
  public function __construct() {
    //注意這里需設置為異步，不然下面無法設置事件回調函數(shù)
    $this->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'));
    //連接服務端
    $this->client->connect('0.0.0.0', 8888);
  }
 
  public function connect($client) {
    echo "connect \n";
  }
 
  public function receive($client, $data) {
    echo "server send: {$data}";
 
    //向標準輸出寫入數(shù)據(jù)
    fwrite(STDOUT, "請輸入消息：");
    //獲取標準輸入數(shù)據(jù)
    $msg = trim(fgets(STDIN));
    //向服務端發(fā)送數(shù)據(jù)
    $client->send($msg);
  }
 
  public function close($client) {
    echo "close \n";
  }
 
  public function error($client) {
    echo "error \n";
  }
}
 
$cli = new EchoClient();
