could you please show us a real usage for this?

It is a WordPress example, and I am already using the New solution:

// Old solution:

class My_Class {

    function method() {
        [...]
        foreach( $things as $index => $thing ) {		
            call_user_func_array(
                array( $this, $thing ),
                array( $arg1, $arg2, $arg3 )
            );
        }
        [...]
    }
}

-------------------------------------------------------------------------------------------
// New solution:

class My_Class {

    function __construct() {
        [...]
        $trait_methods = get_class_methods( 'My_Trait' );
        foreach( $trait_methods as $trait_method ) {
            add_action( "id/$trait_method", array( 'My_Trait', "$trait_method" ), 5, 3 );
        }
        [...]
    }
}

The aim is not to bother My_Class with plenty of methods, I can pick up them, and put them into a separate My_Trait file. And, the other advantage is that the user do not need to dig into the My_Class, it is enough him/her to know the more simpler My_Trait.

you may want to see: http://php.net/manual/en/function.class-uses.php


and works like: get_class_methods(current(class_uses("My_Class")));

Thank you for the hint, but it leads me to complete the example a little bit.
The problem is the method name conflict and the absence of possibility of resolving
them dynamically (or, I do not know the know-how).

Please have a look at the new example which contains three files:
My_Class, My_Trait_Admin, My_Trait_Front.

https://github.com/NaMarPi/php-reports/blob/master/trait_conflict_resolution.php

Sorry, the problem is that that I do not know which trait will be the dominent
at the place of "use My_Trait_Admin, My_Trait_Front".

I have a hard time understanding what it is that you want. As you already pointed out, you can use get_class_methods to get the methods of both classes and traits (and interfaces for that matter). Are you suggesting that we add a get_trait_methods alias? If so, no, that won't be done.

Thank you very much for your time. I come with a strong typing background,
and tend to forget about PHP attributes, sorry for that.
And of course, an alias does not make sense.
