从PHP-MySQL查询的复选框Ping选择的IP
[英]Ping selected IPs from checkbox on PHP-MySQL query
问题描述
我有一个主意，想知道它是否可以在PHP上运行，因为我是PHP新手。 我需要对选定的计算机名称或IP地址执行ping操作，并在ping status框上将其状态设置为联机或脱机。

在此功能中传递ip即可获得主机状态。
<?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4是您希望ping的数目，您可以根据需要在linux系统中进行更改，如果您未设置此值，它将永远ping通。
