代码 swoole_event_add_two.php

<?php
/**

 */
//异步事件

$fp = stream_socket_client("tcp://www.qq.com:80",$errno,$errstr,30);
fwrite($fp,"GET / HTTP/1.1\r\nHOST:www.qq.com\r\n\r\n");
//添加异步事件
swoole_event_add($fp,function ($fp){
   $resp = fread($fp,8192);
   var_dump($resp);
   swoole_event_del($fp);//删除句柄
    fclose($fp);
});
echo "这是先执行完\n";

结果
