enum.magicMethod

Code example

<?php declare(strict_types = 1);

enum Suit: string
{
	case Hearts = 'hearts';
	case Diamonds = 'diamonds';

	public function __get(string $name): mixed
	{
		return null;
	}
}

Why is it reported?

PHP enums are not allowed to contain most magic methods. Only a limited set of magic methods is permitted in enums (__call, __callStatic, __invoke). Methods like __get, __set, __isset, __unset, __serialize, __unserialize, __toString, __clone, and others are forbidden because enums are not meant to be modified or have their behavior customized in ways that could break value semantics.

How to fix it

Remove the disallowed magic method from the enum and use a regular named method instead:

 <?php declare(strict_types = 1);

 enum Suit: string
 {
 	case Hearts = 'hearts';
 	case Diamonds = 'diamonds';

-	public function __get(string $name): mixed
-	{
-		return null;
-	}
+	public function getLabel(): string
+	{
+		return match($this) {
+			self::Hearts => 'Hearts',
+			self::Diamonds => 'Diamonds',
+		};
+	}
 }
