Error Identifier: class.deprecatedAttribute
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]
class Foo
{
}
Why is it reported? #
The PHP 8.4 #[\Deprecated] attribute is designed for functions, methods, and class constants. It cannot be applied to classes, interfaces, or enums. To mark a class as deprecated, use the @deprecated PHPDoc tag instead. Using the #[\Deprecated] attribute on a class has no effect at runtime and indicates a misunderstanding of the attribute’s intended usage.
On PHP 8.5, the #[\Deprecated] attribute can also be used on traits and constants.
How to fix it #
Replace the #[\Deprecated] attribute with a @deprecated PHPDoc tag:
<?php declare(strict_types = 1);
-#[\Deprecated]
+/** @deprecated Use Bar instead */
class Foo
{
}
Non-ignorable error #
This error cannot be ignored using @phpstan-ignore or the ignoreErrors configuration. Non-ignorable errors indicate code that would cause a crash or a fatal error at runtime, or a fundamental problem in the analysed code that must be addressed.
