*nix type shells

You can reconnect to a process by doing fg [job id] (which isn't the PID but you can find it by using the jobs command from terminal)

IPC

You can also send variables into programs if the program is configured to accept it. It may read it off of a pipe, file, or network socket

A program is also able to receive signals (sent with the kill -[signal]) if its simply waiting for a boolean message

For php, sending variables through these methods may involve serialization of the variables prior to transmission

Interprocess communication is often handled by sockets, which are supported in PHP. So if you have control over both applications you can set up sockets to communicate between them.
