assert.deprecatedTrait - Phpstan

Code example

php

<?php declare(strict_types = 1);

/** @deprecated Use NewHelper instead */
trait OldHelper
{
}

class Foo
{
    /**
     * @phpstan-assert OldHelper $value
     */
    public function assertHelper(mixed $value): void
    {
        // ...
    }
}

Why is it reported?

The @phpstan-assert PHPDoc tag references a trait that has been marked with a @deprecated PHPDoc tag. The trait is scheduled for removal or replacement, and any usage of it -- including in assertion type annotations -- should be migrated to the recommended alternative.

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

How to fix it

Replace the deprecated trait with its recommended replacement in the @phpstan-assert tag:

diff-php

 <?php declare(strict_types = 1);

 class Foo
 {
     /**
-     * @phpstan-assert OldHelper $value
+     * @phpstan-assert NewHelper $value
      */
     public function assertHelper(mixed $value): void
     {
         // ...
     }
 }
