PHP RFC: Add typehint accessors to ReflectionParameter


This RFC proposes a class to represent type information; it also adds methods to ReflectionParameter to utilize this information: ReflectionParameter::hasTypeAnnotation() and ReflectionParameter::getTypeAnnotation(). Additionally it adds an explicit __toString method to make parsing function/method signatures and replicating them for mocking frameworks simpler.

Current mocking frameworks have to cast the ReflectionParameter to a string, then text parse that string to retrieve the information.

Proposed PHP Version(s)

5.next (5.7)

New Reflection class type: ReflectionTypeAnnotation

class ReflectionTypeAnnotation implements Reflector {
    public function __toString() { /* returns type annotation string (e.g. "array", "stdClass", etc...) */ }
    public function isArray() { /* true if the typehint is "array" */ }
    public function isCallable() { /* true if the typehint is "callable" */ }
    public function isNullable() { /* true if NULL is an acceptable value */ }

Implementation and new unit test
