How to wake a PC with a PHP script?

By enabling Wake-on-LAN on my PC, I can remotely power it on.

Suppose I want to send the "magic packet" from a PHP scrip开发者_开发技巧t. How would I do this? Would I need to use the cURL functions?

You can peek at: http://sourceforge.net/projects/wolviaphp/files/ (uses fsockopen() with 'udp://')

I have used WMI in the past, for the remote management of machines running windows.

So WMI from MS or http://www.openwbem.org/ (the open standard) might be what you are looking for.

Good luck.
