Php, I cant access inherited private variables not even with reflection

class A
{
    private $a;
}

class B extends A
{
    function __construct()
    {
        (new \ReflectionClass($this))->getProperty('a')->setAccessible(true);
        echo $this->a;
    }
}

(new B());

this should work, altough it triggers an exception: "property a doesnt exists". Many articles says Reflection is the sollution

Private properties and methods belong to a class they were declared.
They're not accessible from the derived class unless you override them

You're passing the ReflectionClass an instance of B, which doesn't have access to $a. What you need is to pass it an instance of A instead. This should help clarify what you need to do here

class A
{
    private $a = 'Bob';
}

class B extends A
{
    function __construct()
    {
        $instance = new A();
        $reflection = new \ReflectionClass($instance);
        $property = $reflection->getProperty('a');
        $property->setAccessible(true);
        echo $property->getValue(new A());
    }
}

(new B());
