Error Identifier: staticProperty.deprecatedInterface
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 NewConfig instead */
interface OldConfig
{
}
class AppConfig implements OldConfig
{
public static string $value = 'default';
}
AppConfig::$value;
Why is it reported? #
This error is reported by the phpstan-deprecation-rules extension.
A static property is accessed on a type that involves a deprecated interface. The interface has been marked with @deprecated and is scheduled for removal or replacement. This error can be triggered when accessing a static property on a class that is typed through a deprecated interface, or when the declaring class of the property is a deprecated interface.
How to fix it #
Use the recommended replacement interface or access the property through a non-deprecated type:
-/** @deprecated Use NewConfig instead */
-interface OldConfig
-{
-}
+interface NewConfig
+{
+}
If the calling code is itself deprecated, the error will not be reported. Mark the function or class as deprecated if it is part of a deprecation migration:
+/** @deprecated */
function doFoo(): void
{
AppConfig::$value;
}
How to ignore this error #
