Is there a way to use singleton [1] classes with webpages?
Basically I want to be able to have classes that are shared for multiple users, so that the class and objects don't have to be recreated.
They way I understand things now, are that all of your classes are destroyed (or at least unavailable) after the web server sends the page.
I have used memcached [2], but it adds a lot of code for classes all the singleton classes that I need. Plus, not all hosts support memcached, which makes the program less portable.
For those of you that don't think it is necessary, or that want more details, read on. I have a GUID [3] class that produces GUIDs for me. This class is set up to only allow one person through at a time (at least I hope), so that the same GUID will never be replicated. I only can have one object of this class in existence at a time or else the the same GUID could be created if both were hit at the same time.
Why a GUID? A GUID is necessary to be able to call things from the cache. Auto_increment on a dbms uses the same set of values for each table. That number cannot be used to reference objects in a cache, so something more detailed needs to be used.
Why a cache? A cache allows me to not hit the database as often. This speeds up the web server.
Why OO [4]? Because it is clean.
