Description:
------------
Certain functions on instances of ReflectionParameter will not return the correct value for core functions.

So far I found out that isArray and isCallable will always return false (as far as I tested) and isPassedByReference and isOptional will return the correct value.

In the test script I used array_key_exists and array_walk and a user definied function array_magic. The difference between the expected and actual result are:

array_key_exists
  search
    isArray
array_walk
  input
    isArray
  funcname
    isCallable

    

Test script:

Expected result:

array_key_exists
  key
    isPassedByReference: false
    isOptional:          false
    isArray:             false
    isCallable:          false
  search
    isPassedByReference: false
    isOptional:          false
    isArray:             true
    isCallable:          false

array_walk
  input
    isPassedByReference: true
    isOptional:          false

  funcname
    isPassedByReference: false
    isOptional:          false
