I have a base abstract class that defines a property to be 
protected and that also checks this runtime using the 
reflection api. 
My purpose is to enforce the extending class to declare 
that property as protected too. 
The reflection api returns me wrong information. It 
returns always that the property is protected (as defined 
in the base class), ignoring the definition of the 
extending class. 

Reproduce code:
abstract class enum {
    protected $_values;

    public function __construct() {
        $property = new ReflectionProperty(get_class($this),'_values');
        if(!$property->isProtected()) {
            throw new Exception("Property _values must be declared as protected");


final class myEnum extends enum {
    public $_values = array(
           0 => 'No value',
           1 => 'Value n.1',
           2 => 'Value n.2',
           4 => 'Value n.4'

$x = new myEnum();

Expected result:
Fatal error: Uncaught exception 'Exception' with message 
'Property _values must be declared as protected' 

Actual result:
No exception is thrown

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

Parent constructor returns information about the parent class, no bug here.

Ilia, the fix is similar to the fix applied to #36308.

The ReflectionProperty class is correctly checking for myEnum->_values property (not for enum->_values) but it returns the visibilty of enum->_values instead of myEnum->_values.

get_class($this) in the enum constructor returns correctly myEnum, so the line "$property = new ReflectionProperty(get_class($this),'_values');" is equivalent to writing "$property = new ReflectionProperty('myEnum','_values');".

The problem remains also if i write this code outside the classes definitions:

$property = new ReflectionProperty('myEnum','_values');
if($property->isProtected()) {
    throw new Exception("Property _values must be declared as

Thank you,
