$serv = new swoole_server(&#39;127.0.0.1&#39;, 9501);

// 监听连接进入事件
$serv->on(&#39;connect&#39;, function ($serv, $fd) {
    echo "Client: Connect.\n";
});

// 监听数据接收事件
$serv->on(&#39;receive&#39;, function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, "Server: " . $data);
});

// 监听连接关闭事件
$serv->on(&#39;close&#39;, function ($serv, $fd) {
    echo "Client: Close.\n";
});

// 启动服务器
$serv->start();

1. Execute the program and start the server

$  /usr/local/php/bin/

2. After successful startup, check netstat

$ sudo netstat -ntlp | grep php     
tcp        0      0 127.0.0.1:9501          0.0.0.0:*               LISTEN      21314/php
