I am starting a process with the system command via a php page. I want
to put a button on the same page which will let the user kill the
process by clicking that button. To do this, I need to know the process
ID. I could grep for it, but that also returns the grep command. How can
I make PHP tell me the process ID of a process I started? It seems as if
this would not be a problem but I guess I am missing something.

Thanks to anyone who can shed some light on this little problem!

Add another grep to the command line, perhaps? Like this:

# ps aux | grep processname | grep -v grep

Excerpt from the manual entry for grep:
---------------------------
-v, --invert-match
Invert the sense of matching, to select non-matching lines.
---------------------------

So adding "grep -v grep" will go through that already grepped list and
return the lines that *don't* contain the process for grep.
