<?php
//创建异步tcp客户端
$client=new swoole_client(SWOOLE_SOCK_TCP,SWOOLE_SOCK_ASYNC);
//注册连接成功的回调函数
$client->on(‘connect‘,function($cli){
    $cli->send("hello \n");
});
//注册数据接收 $cli:服务端信息 $data:数据
$client->on(‘receive‘,function($cli,$data){
    echo "data:$data";
});
//注册连接失败
$client->on(‘error‘,function($cli){
    echo "失败\n";
});
//注册关闭函数
$client->on(‘close‘,function($cli){
    echo "关闭\n";
});
//发起连接
$client->connect(‘192.168.10.1‘,8080,10);
//php index.php
//ps -ajft              //查看启动进程
