There are very, very few things that work in PHP 4 that do not work in
PHP 5. Almost all of the very, very few things are esoteric options that

functions, new suites of functions, and occasional enhancements to
existing functions that are generally enhanced by adding new optional
parameters onto the end end of the list of already optional ones.
