Question: Is there a way to get a list of the traits which a trait is composed of? For reference, I'm refering to traits composed from traits.

Scenario: I have classes for models User, Account and Lead. I have traits called People, Importable, Exportable, Validatable, ImplicitAttributable, Auditable, Listable, Permitable, Searchable, Encryptable, Hashable, Currentable, Relatable and Triggerable. All 3 classes implement the People trait.

The trait called People is composed of Auditable, Listable, Permitable, Searchable, Encryptable, Hashable, Currentable, Relatable and Triggerable.

I am trying to filter my classes by traits. However, when I try to filter the by the trait Searchable, which isn't specifically defined on one of the models (instead it's part of the composed trait People), I get no results.

Current Methods Used:

I've tried to use PHP's class_uses and the following function:

function getTraitsForClass($class)

 return array_keys((new ReflectionClass($class))->getTraits());

to generate the list of traits to filter by. I get the People trait in the list, but I don't get the Searchable trait.

Additional Information:

I'm building my application using Laravel 5.7 with PHP 7.1.23.

It turns out that ReflectionClass can also be used on Traits. So I modified my function to:

function getTraitsForClass($something)

 $traits = array_keys((new ReflectionClass($something))->getTraits());
 foreach ($traits as $trait) 
 $traits = array_merge($traits, getTraitsForClass($trait));
 
 $traits = array_unique($traits);
 return $traits;

And I was able to get the full list of traits.
