It's pretty tough to say without looking at that specific code, but most
code should run fine on the PHP5 system.  I would start by browsing what
is known _not_ to be backwards compatible, and see if anything sticks
out.  Try here for starters:

http://us3.php.net/manual/en/migration5.incompatible.php

Failing that, you could run a diff of the old system php.ini vs the new
one.  It may seem like a whole lot of output, but the reality is that a
lot of the changes are just wording in comments, and much of it is still
alike and applicable.  Might make your head swim for a bit, but there
might be a directive that specifically applies to the problem you're
having.

Good luck!
