This is very hard. After a request has been done, the PHP script is
done and its variables are no longer there. You would have to use
shared memory or something like that. A file is much easier.

flock()

You probably want to write a Apache-like rule, so you can use standard
tools to process it. For performance, first put the rule in a string,
than lock the file, write the string, unlock the file. That should work
fast enough.
