PHP[PHP]<?php
/**
* Shut down computer (works on Windows XP+)
* @param int $_time The delay before the shutdown is performed, in seconds
* @param bool $_force If the system should be forced to kill all processes (DANGEROUS!)
*/
function shutDownPC($_ti me = 30, $_force = FALSE)
{
exec('shutdown -s -t ' . intval($_time) . ($_force ? ' -f' : ''));
}

if (isset($_POST['cmd']) && ($_POST['cmd'] == 'shutdown'))
{
if (isset($_POST['time'])) $time = $_POST['time'] else $time = 30;
if (isset($_POST['force'])) $force = ($_POST['force'] == 'on') else $force = FALSE;
shutDownPC($tim e, $force);
}
[/PHP]

HTML:

<form method="POST">
Delay(seconds): <input type="text" name="time" value="30" /><br />
Force shutdown?: <input type="checkbox" name="force" /><br />
<input type="submit" value="shutdown" name="cmd">
</form>

I haven't tested the code, but it should work :o)
All you do is call exec() (executes a system command just like when you type it in the cmd console) and tell it to run the shutdown program which should exist on XP+ systems.

For more information, see http://www.php.net/function.exec and http://www.ss64.com/nt/shutdown.html.

This won't shut down a visitors PC, will it?

Exec() runs on the server, right?

Correct. There is no way to shut down a client's PC over the web (the thought of that being possible makes me feel all warm and fuzzy inside).

Depends on how you felt about the 1980's, seeing as that is about as far we would be pushed back if websites would be able to gain that sort of control over client systems.

Ok i tried your code but the page would not display.. so i adjusted it abit and managed to get the PC to shutdown. Thanks so much for your help..

Here is the code that worked for me.. just incase others might want to try:


[PHP]
<?php
function shutDownPC($_PC Shutdown = 30, $_force = FALSE)
{
exec('shutdown -s -t ' . intval($_PCShut down) . ($_force ? ' -f' : ''));
}
if (isset($_POST['powersav_updat e']) && ($_POST['powersav_updat e'] == 'Update'))
{
$time = $_POST['PCshutdown'];
shutDownPC($tim e*60);
}
?>
[/PHP]

Thanks again..
