OverriddenPropertyAccess

A child class declares a property with the same name as a parent property but with a more restrictive visibility. PHP does not allow reducing the visibility of a property when overriding.

Example

<?php
class Base {
    public string $name = '';
}

class Child extends Base {
    protected string $name = ''; // reduces visibility from public to protected
}

How to fix

Keep the visibility at least as permissive as the parent property, or rename the property in the child class.
