1.2.1400. Useless Override Attribute

The override attribute is only useful on an extended class. It allows to mark a method that must be overriding a parent method. When the class is not extending another class, there is no point in using this attribute.

This is also valid with extended class : the top parent class has no use of the override.

There is a dedicated compile-time error.

<?php

class x {
     // override in that trait are useless
     use t;

     // This is useless
     #[Override]
     function foo() {}
}

trait t {
     // This is useless if loaded in a root class
     #[Override]
     function foo() {}
}

enum e {
     // This is useless in any case
     #[Override]
     function foo() {}
}


?>
