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 ).
