enum.destructor

Code example

<?php declare(strict_types = 1); // lint >= 8.1

enum Suit
{
	case Hearts;
	case Diamonds;

	public function __destruct()
	{
	}
}

Why is it reported?

PHP enums cannot have destructors. Enum cases are singleton values managed by the engine and are not subject to normal object lifecycle. Defining __destruct in an enum is a compile-time error in PHP.

How to fix it

Remove the destructor from the enum:

 enum Suit
 {
 	case Hearts;
 	case Diamonds;
-
-	public function __destruct()
-	{
-	}
 }

If cleanup logic is needed, move it to a separate class that uses the enum rather than defining it on the enum itself.
