Hi Michael,
I've never used it myself, but this may be of some use:
http://www.php.net/manual/en/ref.shmop.php
If I understand it correctly, this lets you write a string into an area of
memory which can be accessed from any process - i.e. another httpd process.
If you wanted to save an array you would need to serialize() it first.
Cheers
Simon Garner
