(PHP 8 >= 8.3.0)
This attribute is used to indicate that a method is intended to override a method of a parent class or that it implements a method defined in an interface.
If no method with the same name exists in a parent class or in an implemented interface a compile-time error will be emitted.
<?php
class Base {
protected function foo(): void {}
}
final class Extended extends Base {
#[\Override]
protected function boo(): void {}
}
?>В PHP 8.3 поданий вище приклад виведе щось схоже на:
Fatal error: Extended::boo() has #[\Override] attribute, but no matching parent method exists
