attribute.deprecatedClass

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewAttribute instead */
#[\Attribute]
class OldAttribute
{
}

#[OldAttribute]
class Foo
{
}

Why is it reported?

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

An attribute references a class that has been marked as @deprecated. Using deprecated attribute classes means your code relies on attributes that are planned for removal.

In the example above, the #[OldAttribute] attribute uses the deprecated OldAttribute class.

How to fix it

Replace the deprecated attribute with its recommended replacement:

 <?php declare(strict_types = 1);

-#[OldAttribute]
+#[NewAttribute]
 class Foo
 {
 }
