PHP doesn't have persistance at the application level. There are a
few things that you're embarking on that doesn't smell right to me.
First, you'll have to pass those values from request to request, more
code (introducing bugs and maintenance nightmares) and overhead on the
webserver. Second, you're polluting your namespace with variables you
probably won't need in that request, introducing bugs and maintenance
nightmares. Have you tried using mysql as your storage persistance to
see how slow it really is? Typically, it isn't much at all, and it
makes life so much easier. For some variables, you can use, and
should, use $_SESSIONS...but there's no need to overdo it.
If you're REALLY sure that application scope persistance is what you
want, however, try looking up the REGISTRY design pattern. Good to
know, but it comes with it's own problems.
