If you are actually forking (as opposed to exec'ing a new process), then
forked processes share filehandles with their parent, so that's one way to
communicate between them. Other methods may include:

Simple command line parameters? http://php.net/system
Pass data via stdin/stdout? http://php.net/proc_open
Sockets? (UNIX, TCP, etc.) http://php.net/sockets

Or see http://en.wikipedia.org/wiki/Inter-process_communication for more.
