Require_once(_)...when does it reset?

I am playing with PEAR_Info on my server. It was working fine, then I upgraded some classes, now it is not. I think it is because PHP is holding on to the old code from some require_once functions. I may be totally wrong but that is all I can think of what would cause this. Other classes (that I did not execute before updating) work fine. Is there a way to reset PHP if this is the case?
