enumImplements.class - Phpstan

Code example

php

<?php declare(strict_types = 1);

class SomeClass
{
}

enum Status implements SomeClass
{
	case Active;
}

Why is it reported?

An enum uses implements to reference a class instead of an interface. In PHP, enums can only implement interfaces. Attempting to implement a class will cause a fatal error.

How to fix it

Replace the class with an interface:

diff-php

 <?php declare(strict_types = 1);

-class SomeClass
+interface SomeInterface
 {
 }

-enum Status implements SomeClass
+enum Status implements SomeInterface
 {
 	case Active;
 }
