PHP - 让服务器ping访问者IP并以ms为单位返回ping [英] PHP - get server to ping a visitors IP and return the ping in ms

问题描述

我想按标题说明。要ping用户IP并以ms为单位返回结果，例如：

I want to do as the title states. To ping a users IP and return a result in ms, for instance:

Ping IP
返回400ms。

Ping IP return 400ms.

我不知道怎么做但我希望它会相对简单。我可以访问exec（）函数和类似的函数，因为我将在虚拟专用服务器上运行此脚本。

I have no idea how to do this but I expect it would be relatively simple. I have access to the exec() function and the functions similar to it as I will be running this script on a virtual private server.

提前致谢。

推荐答案

试试这个

<?php

$out = array();
exec('ping -c 4 '.$_SERVER['REMOTE_ADDR'], $out);
print_r($out);

?>
