PHP中通过system()调用系统ping命令验证服务器的连接性

风神

验证服务器的连接性是一个常见的任务，我们也可以通过PHP的system()函数调用系统的ping命令来完成这个任务，源码如下：

1. <?php
   
2.         $server="www.wphostz.net";
   
3.         $count=3;
   
4.         echo "<pre>";
   
5.         system("/bin/ping -c $count $server");
   
6.         echo "</pre>";
   
7.         system("killall -q ping");
   
8. ?>

复制代码

效果如下:

PING www.wphostz.net (50.22.130.187) 56(84) bytes of data.
32 bytes from 50.22.130.187: icmp_seq=1 ttl=51 time=210 ms
