requireImplements.deprecatedTrait

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewTrait instead */
trait OldTrait
{
}

/**
 * @phpstan-require-implements OldTrait
 */
trait MyTrait
{
}

Why is it reported?

The @phpstan-require-implements PHPDoc tag references a trait that has been marked with @deprecated. Using deprecated symbols leads to issues when they are eventually removed. PHPStan reports this so that the reference can be updated to the recommended replacement.

This error is reported by phpstan/phpstan-deprecation-rules.

How to fix it

Replace the deprecated trait with its recommended replacement:

 <?php declare(strict_types = 1);

 /**
- * @phpstan-require-implements OldTrait
+ * @phpstan-require-implements NewInterface
  */
 trait MyTrait
 {
 }
