new.deprecatedEnum

Code example

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

/** @deprecated Use NewStatus instead */
enum OldStatus
{
	case Active;
}

$x = new OldStatus();

Why is it reported?

This error is reported by the phpstan-deprecation-rules extension.

A deprecated enum is used in a new expression. Deprecated enums are planned for removal in a future version.

Note: triggering this identifier requires instantiating an enum, which PHP does not allow. PHPStan therefore always also reports a new.enum error, and in practice the deprecation identifier is not reported alongside it.

How to fix it

Enums cannot be instantiated. Use enum cases directly instead:

-$x = new OldStatus();
+$x = NewStatus::Active;
