 New Comment:

I have a very strong feeling about this.
I understand that the PHP implementation of traits is about copying traits into 
classes. Yet, the whole purpose of a Reflection API is to find where properties 
/ methods are declared.

I have a simple question: I need to be able to find in which class/trait a 
method is declared. I need this for my PHP framework (Mouf), that is heavily 
relying in reflection to build a graphical dependency injection system.

I've written a lengthy blog post explaining what the problems with the current 
Reflection API are, and hopefully, how to find a (not perfect) work around.

You can find the blog post here: 
http://mouf-php.com/blog/php_reflection_api_traits

I really hope we can agree this is indeed something that needs to be fixed, as 
the workaround I've put in place are far from perfect.

For technical details, my PHP version: PHP 5.4.9-4ubuntu2.1.

In that case should there not be some kind of isTrait for the ReflectionMethod 
the same way there is for the ReflectionClass?

the methods of traits are copied into class.

so, in theory, there is nothing wrong.

Description:
------------
Specific PHP version PHP 5.4.15-1~dotdeb.2

Executing ReflectionClass::getMethods on a class using traits does not 
differentiate between methods within the class or methods within the trait 
being 
used, whereas calling ReflectionMethod::getDeclaringClass on the class with the 
method identifies it as coming from the trait.

Test script:
---------------
<?php

trait t {
    function f() {
        //do stuff
    }
}

Class c {
    use t;

    function f2() {
        //do stuff
    }
}

$class = new ReflectionClass('c');
print_r($class->getMethods());
?>

Expected result:
----------------
Array
(
    [0] => ReflectionMethod Object
        (
            [name] => f2
            [class] => c
        )

    [1] => ReflectionMethod Object
        (
            [name] => f
            [class] => t
        )

)

or

Array
(
    [0] => ReflectionMethod Object
        (
            [name] => f2
            [class] => c
        )

    [1] => ReflectionMethod Object
        (
            [name] => f
            [trait] => t
        )

)

Actual result:
--------------
Array
(
    [0] => ReflectionMethod Object
        (
            [name] => f2
            [class] => c
        )

    [1] => ReflectionMethod Object
        (
            [name] => f
            [class] => c
        )

)
