get_parent_class

We can get the parent class for an object in Ruby by first referencing the class object using the Object#class. Once we have the class object, we can use the Class#superclass method to find the superclass.

{{code:php
class Dinosaur {} class TRex extends Dinosaur {}

$t = new TRex;
$result = get_parent_class($t);
var_export($result);
// => 'Dinosaur'

}}

{{code:ruby class Dinosaur; end class TRex < Dinosaur; end

t = TRex.new
p t.class.superclass
# => Dinosaur

}}
