PHP使用swoole编写简单的echo服务器代码示例

本篇文章小编给大家分享一下PHP使用swoole编写简单的echo服务器代码示例，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

server.php代码如下：

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.php代码如下：

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();

然后分别运行这两个脚本

> /data/php56/bin/php server.php
> /data/php56/bin/php client.php

运行结果如下：
