[PHP] PHP 5 Backwards Compatability

[Tod Thomas]

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


Thanks.

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.
