property.deprecatedTrait

Code example

<?php declare(strict_types = 1);

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

class Foo
{
	/** @var OldHelper */
	public $helper;
}

Why is it reported?

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

A property has a PHPDoc type that references a trait marked as @deprecated. Deprecated traits are planned for removal in a future version, and property types should not rely on them.

How to fix it

Replace the deprecated trait with a non-deprecated type:

 class Foo
 {
-	/** @var OldHelper */
+	/** @var NewHelper */
 	public $helper;
 }
