requireExtends.deprecatedEnum

Code example

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

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

/**
 * @phpstan-require-extends OldStatus
 */
interface StatusAware
{
}

Why is it reported?

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

The @phpstan-require-extends PHPDoc tag references a deprecated enum. Deprecated enums are planned for removal in a future version.

Note: triggering this identifier requires @phpstan-require-extends to reference an enum, which is not valid. PHPStan therefore always also reports a requireExtends.enum error, and in practice the deprecation identifier is not reported alongside it.

How to fix it

Replace the deprecated enum with a proper class reference:

 /**
- * @phpstan-require-extends OldStatus
+ * @phpstan-require-extends NewBaseClass
  */
 interface StatusAware
 {
 }
