staticProperty.deprecatedInterface

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewConfig instead */
interface OldConfig
{
}

echo OldConfig::$value;

Why is it reported?

This error is reported by the phpstan-deprecation-rules extension.

A static property is accessed directly on an interface that has been marked as @deprecated. Deprecated interfaces are planned for removal in a future version, and code should not access static properties on them.

How to fix it

Use the recommended replacement interface or access the property through a non-deprecated type:

-echo OldConfig::$value;
+echo NewConfig::$value;
