PHP OOP get all parent classes of a class

Question

I have class Mercedes and it has parent Car and Car has parent Main.
I want to get all parents from Mercedes Class

Mercedes extends Car 
Car extends Main

output should be something like this mercedes<-Car<-Main

Answer 1

This would do:

function GetAllParents(instance) {
   return get_class(instance) . '<-' .
          implode('<-', array_reverse(class_parents(instance)));
}

Outputs all in the right order:

Mercedes<-Car<-Main

See documentation:
