1.2.463. Final Private Methods

PHP’s private methods cannot be overwritten, as they are dedicated to the current class. That way, the final keyword is useless.

PHP 8.0 warns when it finds such a method.

<?php

class foo {
    // Final and private both prevent child classes to overwrite the method
    final private function bar() {}

    // Final and protected (or public) keep this method available, but not overwritable
    final protected function bar() {}
}

?>
