Error Identifier: classConstant.internal
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;
class Config
{
/** @internal */
public const DEBUG_MODE = true;
public const VERSION = '1.0';
}
<?php declare(strict_types = 1);
// In your code:
use SomeLibrary\Config;
echo Config::DEBUG_MODE;
Why is it reported? #
The class constant is marked as @internal and is being accessed from outside the package where it is defined. Internal constants are not part of the package’s public API and may change or be removed without notice.
How to fix it #
Use a public (non-internal) constant or API instead:
<?php declare(strict_types = 1);
use SomeLibrary\Config;
-echo Config::DEBUG_MODE;
+echo Config::VERSION;
If no public alternative exists, consider reaching out to the package maintainers to request a public API for your use case.
