Is their a list of portability problems to be aware of when switching from v4 to v5? Maybe a table that compares the two?

other than the stuff on php.net (no comparison tables exactly) not really - plenty of people on this list that will help you if you run into problems. sidenote: the reference related fixes introduced into php4.4 (and php5+) can be a PITA, avoid using references unless you.. a, really know what you are doing. b, you really need a reference. ...objects in php5 don't need to be passed around by reference - in fact I suggest the first thing you do when updating your code is to remove reference syntax related to passing around objects :-)

Thanks.
