exec() and &

Question posted by: Bryan Andrews (Guest) on March 15th, 2008 01:55 AM

At the shell you can always type "rm -rf /tmp/* &" and let the delete
command run in the background. Is there a way to do this from a php
shell script?

I've tried `rm -rf /tmp/* &` ... but with the backticks it still
waits for the command to finish before moving on to the next. I've
also tried exec() with no luck. Anyone know any tricks?

It's not really threading, but you can escape the parent process while
the child is running.
