Well, on unix, you could use the (still experimental, according to
the docs) shared memory functions:
http://php.he.net/manual/en/ref.shmop.php
There's also the apparently more mature, but less portable
semaphore/shared memory functions (also Unix only) here:
http://php.he.net/manual/en/ref.sem.php
I've never used either of these.
Maybe you could explain what you're trying to do a bit more (and what
platform you're on). I can't see where loading separate copies of the
variables would be much of a memory issue, unless you have large
numbers of variables, very long strings stored there, and hundreds of
apache child processes.
