swoole初识

server.php

<?php
//创建Server对象，监听 127.0.0.1:9501端口
$serv = new swoole_server("127.0.0.1", 9501); 

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

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

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

//启动服务器
$serv->start(); 

client.php

<?php

$client = new swoole_client(SWOOLE_SOCK_TCP);

//连接到服务器
if (!$client->connect('127.0.0.1', 9501, 0.5))
{
    die("connect failed.");
}
//向服务器发送数据
if (!$client->send("hello world"))
{
    die("send failed.");
}
//从服务器接收数据
$data = $client->recv();
if (!$data)
{
    die("recv failed.");
}
echo $data;
//关闭连接
$client->close();
