Having migrated some of my applications to PHP5, I can reassure you by 
saying that PHP5 is mostly backward-compatible with PHP4's OO syntax. 
One of the main differences lie not in the OO syntax, but in a few 
modules and functions, such as mysql functions, which must all be 
migrated to "mysqli". To correctly write PHP5 OO code, you'll need to 
modify your existing classes to take advantage of the many new features 
that are available, but overall the migration is quite straight-forward.

Don't hesitate to write about some specific problems you may encounter.
