generics.deprecatedEnumBound

Code example

<?php declare(strict_types = 1);

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

/**
 * @template T of OldStatus
 */
class StatusHandler
{
}

Why is it reported?

The @template tag uses a deprecated enum as its bound constraint (T of OldStatus). The enum OldStatus is marked as @deprecated, meaning it should no longer be used and may be removed in a future version.

This rule is provided by the phpstan-deprecation-rules extension.

How to fix it

Replace the deprecated enum with its recommended replacement:

 /**
- * @template T of OldStatus
+ * @template T of NewStatus
  */
 class StatusHandler
 {
 }
