Question

I’m trying to read protected vars by called class. Where is the problem with my protected $test and new ReflectionClass?

<?PHP
class foo
{
    protected $test = ['foo' => 'foo'];
    public function __construct()
    {
        $class = get_called_class();

        do
        {
            foreach((new \ReflectionClass($class))->getDefaultProperties() as $property => $value)
                var_dump([$class.'::'.$property => $value]);
        }
        while($class = get_parent_class($class));
    }
}

class baz extends foo
{
    protected $test = ['baz' => 'baz'];
}

new baz;

actual:

  ["baz::test"]=>
    ["baz"]=> "baz"
  ["foo::test"]=>
    ["baz"]=> "baz"

expected:

  ["baz::test"]=>
    ["baz"]=> "baz"
  ["foo::test"]=>
    ["foo"]=> "foo"

Kind regards.

There is no problem. The $test class variable in your parent class is set to:

array
(
   'foo' => 'foo'
)

And the child class which inherits it overrides the value of the array (it doesn’t add to the array, but replaces all the existing keys/values) with:

array
(
   'baz' => 'baz'
)
