PHP使用swoole编写简单的echo服务器示例

浅沫记忆

这篇文章主要介绍了PHP使用swoole编写简单的echo服务器,结合实例形式分析了基于swoole的echo服务器客户端与服务器端相关实现技巧及操作注意事项,需要的朋友可以参考下
本文实例讲述了PHP使用swoole编写简单的echo服务器。分享给大家供大家参考，具体如下：
server.php代码如下：

<?php
class EchoServer {
  protected $serv = null;
 
  public function __construct() {
  $this->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：

<?php
class EchoClient {
  protected $client = null;
 
  public function __construct() {
  //注意这里需设置为异步，不然下面无法设置事件回调函数
  $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'));
  //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：

希望本文所述对大家PHP程序设计有所帮助。
