Possible to check to see if Windows process is running from PHP?

[wrybread]

I need to check the state of a processes from within a PHP script on a
Windows machine. All I need to know is whether or not the process
exists (i.e., is running). Anyone have any ideas?

I searched the archives and found proc_open(), but if it can do what
I'm trying to do, I can't figure out how.

Google for tlist.exe (pre-XP) or tasklist.exe (XP).

There's also some goodies here that may be of use:

Thanks so much, that pslist did the trick perfectly.

Curious. Why do you need to do this?
What processes runnng in Windows are you interested in?

I built a photobooth, and PHP does the scripting. So the PHP script
(running in Windows) tells a program called PSRemote to take 4
pictures, then PHP passes the pictures to a Photoshop droplet to
arrange them in a strip, then prints them, then the PHP script uploads
the pics.

The problem is, if someone clicked the button to take more pics while
the script was running, it would crash. So a kludgey solution was to
check if the processes php.exe was running, and if so abort. In essence
I'm preventing multiple instances of the script.

Here's the photobooth, if you're interested:
