Error Identifier: classConstant.internalTrait
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);
// In package vendor/some-library:
namespace SomeLibrary;
/** @internal */
trait InternalTrait
{
public const INTERNAL_VALUE = 42;
}
class PublicClass
{
use InternalTrait;
}
<?php declare(strict_types = 1);
// In your code:
use SomeLibrary\PublicClass;
echo PublicClass::INTERNAL_VALUE;
Why is it reported? #
The constant is defined on a trait that is marked as @internal. Internal types are not part of the package’s public API and may change or be removed without notice. Accessing constants on internal traits from outside their package creates a fragile dependency.
How to fix it #
Use a public (non-internal) constant or API instead. If no public alternative exists, consider reaching out to the package maintainers to request a public API for your use case.
How to ignore this error #
You can use the identifier classConstant.internalTrait to ignore this error using a comment:
// @phpstan-ignore classConstant.internalTrait
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:
