8.swoole学习笔记--异步tcp客户端

Posted 2020-10-24 邹柯

<?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
//service iptables stop //关闭防火墙
?>

注:本地无法进行异步的效果演示
