staticProperty.deprecatedClass

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewConfig instead */
class OldConfig
{
	public static string $value = 'default';
}

echo OldConfig::$value;

Why is it reported?

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

A static property is accessed on a class that is marked as @deprecated. Deprecated classes are planned for removal in a future version, and code should not rely on them.

How to fix it

Use the recommended replacement class:

 <?php declare(strict_types = 1);

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