I think my eclipse's ctrl+clicking links might benefit greatly...
Edit: I'm using eclipse PDT.
Edit 2: I'm very happy with the solution of putting docblocks before functions (and variables) with an @return or @var statement, I've just updated the documentation of my app and now eclipse is showing me what functions are available to what objects!
Awesome.
works perfectly with Eclipse PDT. Which plugin do you use?
The only way to hint return type in PHP is to use a good IDE like Eclispe PDT or Zend Studio with standard comment block. PHP simply can n not predict return type because it is dynamically typed language so type checking is done in the run time unlike for the statically typed languages like C#, JAVA and C++.
Short answer: no.
Long answer: consider adding docblocks with @return declarations.
