-====== PHP RFC: Add typehint accessors to ReflectionParameter ====== 
-  * Version: 1.0 
-  * Date: 2014-05-29 
-  * Author: Sara Golemon, pollita@php.net 
-  * Status: Under Discussion 
-  * First Published at: http://wiki.php.net/rfc/reflectionparameter.typehint 
  
-===== Introduction ===== 
- 
-This RFC proposes some improvements to the way we handle type information in reflection. This work will make it easier for writing tools that render type information from reflection. If the [[returntypehinting|Return Type RFC]] is accepted this RFC also unifies the reflection API for type information for both parameters and return types. 
- 
-===== Proposal ===== 
- 
-This RFC proposes a new class ''ReflectionTypeAnnotation'' to represent type information. This RFC adds methods to ''ReflectionParameter'' to use this new class: <php>ReflectionParameter::hasTypeAnnotation()</php> and <php>ReflectionParameter::getTypeAnnotation()</php>. If the Return Type RFC is accepted it will then it will also use this new ''ReflectionTypeAnnotation'' class. 
- 
-The class ''ReflectionTypeAnnotation'' also has ''%%__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 ===== 
- 
-<PHP> 
-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 */ } 
-} 
-</PHP> 
- 
-===== Implementation and new unit test =====

-Original proposal: https://github.com/sgolemon/php-src/commit/d352793a69eb549ffe4b04c4b5dedae2cd4ed831
