property.parentPropertyFinal

Code example

<?php declare(strict_types = 1);

class Base
{
	final public string $name = 'base';
}

class Child extends Base
{
	public string $name = 'child';
}

Why is it reported?

The child class overrides a property that is declared as final in the parent class. Final properties cannot be overridden by child classes. This is a PHP language-level restriction enforced since PHP 8.4.

Properties declared with private(set) visibility are also implicitly final, because the set operation cannot be overridden.

How to fix it

Remove the overriding property declaration from the child class:

 class Child extends Base
 {
-	public string $name = 'child';
 }

If the child class needs different behavior, ask the parent class maintainer to remove the final keyword, or use a different property name:

 class Child extends Base
 {
-	public string $name = 'child';
+	public string $displayName = 'child';
 }
