tcp server

<?php

/**
 * Class Tcp
 * Tcp服务
 */
class Tcp {
    CONST HOST = "0.0.0.0";
    CONST PORT = 9501;

    public $tcp = null;
    public function __construct()
    {
        $this->tcp = new swoole_server(self::HOST, self::PORT);
        $this->tcp->set(
            [
                'worker_num' => 6,
                'max_request' => 10000,
            ]
        );
        $this->tcp->on('connect', [$this, 'onConnect']);
        $this->tcp->on('receive', [$this, 'onReceive']);
        $this->tcp->on('close', [$this, 'onClose']);

        $this->tcp->start();
    }

    /**

    }

    /**

        $tcp->send($fd, $sendData);
    }

    /**

开启服务：

☁  server [master] ⚡ php tcp.php
[2018-04-30 14:41:23 @69315.0]  TRACE   Create swoole_server host=0.0.0.0, port=9501, mode=3, type=1

使用telnet连接

☁  client [master] ⚡ telnet 127.0.0.1 9501
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
hello swoole
服务端将客户端发送的数据原样返回：hello swoole

自定义 tcp client

tcp_client.php

<?php

/**
 * Class TcpClient
 * Tcp客户端
 */
class TcpClient
{
    const HOST = "127.0.0.1";
    const PORT = 9501;

    public $client = null;

    public function __construct()
    {
        $this->client = new swoole_client(SWOOLE_SOCK_TCP);
        $this->connect();
    }

    public function connect()
    {
        if(!$this->client->connect(self::HOST, self::PORT)) {
            echo '连接失败';
            exit;
        }
    }

    public function send()
    {
        fwrite(STDOUT, '请输入消息：');
        $msg = trim(fgets(STDIN));
        $this->client->send($msg);
    }

    public function receive()
    {
        $result = $this->client->recv();
        echo $result . "\n";
    }
}

$client = new TcpClient();
$client->send();
$client->receive();

执行结果：

☁  client [master] ⚡ php tcp_client.php
请输入消息：swoole  tcp 客户端测试
服务端将客户端发送的数据原样返回：swoole tcp 客户端测试
