PHP使用swoole编写简单的echo服务器示例
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。
