<?php

class Foo

class Bar extends Foo
{
}

class Baz extends Bar
{
}

$fooClass = new ReflectionClass('Foo');
var_dump($fooClass->getParentClass());
// bool(false)

$barClass = new ReflectionClass('Bar');
var_dump($barClass->getParentClass());
/*
object(ReflectionClass)#3 (1) {
  ["name"]=>
  string(3) "Foo"
}
*/

$bazClass = new ReflectionClass('Baz');
var_dump($bazClass->getParentClass());
/*
object(ReflectionClass)#4 (1) {
  ["name"]=>
  string(3) "Bar"
}
