This method can be used to call a overwritten public method of a parent class on an child instance
The following code will output "A":

<?php

class A
{
    public function
foo()
    {
        return
__CLASS__;
    }
}

class
B extends A
{
    public function
foo()
    {
        return
__CLASS__;
    }
}

$b = new B();

$reflection = new ReflectionObject($b);

$parentReflection = $reflection->getParentClass();

$parentFooReflection = $parentReflection->getMethod('foo');

$data = $parentFooReflection->invoke($b);

echo
$data;

?>

Seems that Reflection doesn`t resolve late static bindings - var_dump will show "string 'a' (length=1)".

<?php
class ParentClass { protected static $a = 'a'; static public function init() { return static::$a; } }
class
ChildClass extends ParentClass { protected static $a = 'b'; }
   
$r = new ReflectionClass('ChildClass');
var_dump($r->getMethod('init')->invoke(null));
?>

Note: If you want to invoke protected or private methods, you'll first have to make them accessible using the setAccessible() method (see http://php.net/reflectionmethod.setaccessible ).
