WTF?? PHP is just a language, and the parser / interpreter for it. The parser does not highlight syntax, no matter which version are you using. IDEs and editors will apply syntax highlighting, but this will depend on the editor itself, and not at all on the version of PHP being used (actually, most editors won't even "know" which version of PHP is that code).

something more relevant like php4 and php5...
