Delete vars when finished

[groundup]

Thinking about a couple of my scripts and they would definately use the standard 8mb of memory if I didn't remove the variables (especially global) when I was finished.  They just eat and eat up memory.  Then I thought about people having problems with too much mem usage from PHP (8mb usually).  I figure that it must have something to do with including files and such.  So rather than having people come across these bugs in the future, why not initiate the variables with $var = '' and end the function the same way

Memory should be cleared automatically, it's PHPs job to clean up the garbage not ours
