1.2.144. Class Without Parent¶

Classes should not refer to parent when it is not extending another class.

In PHP 7.4, it is a Deprecated warning. In PHP 7.3, it was a Fatal error, when the code was eventually executed. In PHP 8.0, PHP detects this error at compile time, except for parent keyword in a closure <https://www.php.net/`closure>`_.

parent usage in trait is detected. It is only reported when the trait is used inside a class without parent, as the trait may also be used in another class, which has a parent.

<?php

class x {
    function foo() {
        parent::foo();
    }
}
?>
