Error Identifier: attribute.deprecated

Every error reported by PHPStan has an error identifier. Here’s a list of all error identifiers. In PHPStan Pro you can see the error identifier next to each error and filter errors by their identifiers.

Code example #

<?php declare(strict_types = 1);

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

#[OldAttribute]
class Foo
{
}

Why is it reported? #

An attribute references a class that has been marked as deprecated. Using deprecated attribute classes means the code relies on attributes that are planned for removal in a future version.

In the example above, the #[OldAttribute] attribute uses the OldAttribute class which is marked as @deprecated.

How to fix it #

Replace the deprecated attribute with its recommended replacement:

 <?php declare(strict_types = 1);
 
-#[OldAttribute]
+#[NewAttribute]
 class Foo
 {
 }

How to ignore this error #

You can use the identifier attribute.deprecated to ignore this error using a comment:

// @phpstan-ignore attribute.deprecated
codeThatProducesTheError();

You can also use only the identifier key to ignore all errors of the same type in your configuration file in the ignoreErrors parameter:

parameters:
	ignoreErrors:
		-
			identifier: attribute.deprecated
