The biggest difference between PHP4 and PHP5 is in the language support for object-oriented (OO) programming. The PHP5 OO support is far superior in all ways to PHP4, but in order to make such a dramatic improvement, certain regrettable language decisions in PHP4 had to be "corrected." This led to some incompatibilities that can effect scripts using OO techniques. However, most PHP4 scripts, even those using OO language features, will run quite happily in PP5 with little or no modification.
