Question

我有一个想法，想知道它是否可以在PHP上，因为我是PHP的新手。我需要ping所选的计算机名称或IP地址，并将ping状态框的状态设置为在线或离线。

Answer 1

在此功能中传递ip，它给出主机的状态。

 <?php

    function ping_host($host){
    exec("ping -c 4 " . $host, $output, $result);
     return $result==0?"online":"offline";

    }

    echo ping("www.google.com"); // function call

   ?>

注意：这里有4个你希望你可以根据Linux系统的要求改变的ping数量，如果不设置它将永远ping。
