start/kill process

[Anon]

How can I execute process in unix so that I'm able to kill it later by basis of PID number.

I've done this one Windows. What's the problem?

You can:

a) list all processes (ps -u httpd_user), pick the one you desire, parse the PID out and kill the process (kill -9 pid)

b) keep the list of started processes in DB (or plaintext file) and pick PID from there

I'm not sure about user rights on Unix, but if PHP started some process I don't see why it shouldn't be able to kill it as well.
