Hopefully not. We will see when the voting commences. :) > > With return type hinting I can see a huge improvenets in php IDEs in > spotting errors.

With the introduction of parameter type hinting 5.0, and return type hinting following its lead, we will set ourselves up for a good base for a type hinting API and structure. That said, PHP is not Java, and type hinting in PHP is very different. It is, in fact, type *hinting*. This is a runtime feature. Only interface validation is verified at compile time, so we have to consider performance vs. feature in these cases. > > Also, is there an implicit "void" return type? The following types are allowed for both parameters and method returns: - Callable - Object (class name) - Array By not declaring a type hint with a parameter, it is considered mixed. With method returns, simply using the keyword "function" as you have been will signify mixed as well. > > I hope that declaring types of variables will be added too because without > it, this feature is not all that useful. > > Dmitri Snytkine > Web Developer > Ultra Logistics, Inc. > Phone: (888) 220-4640 x 2097 > Fax: (888) 795-6642 > E-Mail: dsnytk...@ultralogistics.com > Web: www.ultralogistics.com > > "A Top 100 Logistics I.T.
