new.enum

Code example

<?php declare(strict_types = 1);

enum Suit
{
	case Hearts;
	case Diamonds;
	case Clubs;
	case Spades;
}

$suit = new Suit(); // error: Cannot instantiate enum Suit.

Why is it reported?

Enums in PHP cannot be instantiated using the new keyword. Enum cases are predefined singleton instances and must be accessed directly via their case names (e.g., Suit::Hearts). Attempting to use new on an enum will result in a fatal error at runtime.

How to fix it

Use the enum case directly instead of trying to instantiate it.

-$suit = new Suit();
+$suit = Suit::Hearts;
