I haven't tried PHP 5 yet for compatibility concerns but the main changes between 4 and 5 are in their object-oriented implementations. So if you use a lot of classes and objects in you code (like me), expect to spend a fair amount time going back through code and making adjustments. Especially tricky are object references (default in PHP5, used the & operator in PHP 4), copying objects (clone function in PHP5), constructors and destructors and so on. But if you mainly used PHP as a proceedural language, I don't think there should be any significant problem.
