Um, that's a pretty broad question.  Yes, there's quite a lot.  No, most 
existing core functions are still the same -- it is still PHP, and most 
PHP4 scripts will run just fine under PHP5.  A few extensions got moved 
into PECL, a bunch of new stuff got added.  An essential (imho) book 
might help:
