Capture a PID as a Variable

[Living2007]

I'm writing a small program which involves a background process. I'm using the "&" attribute with UNIX and it prints the PID, but not in the script. I know it's been stored somewhere, but I want to capture the PID, so when the user want to close the script, the background process is killed by that stored PID!

background_process &
PID="$!"
