Error Identifier: staticProperty.deprecated
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);
class Foo
{
/** @deprecated Use getInstance() instead */
public static $instance;
}
Foo::$instance;
Why is it reported? #
This error is reported by the phpstan-deprecation-rules extension.
A static property marked as @deprecated is being accessed. Deprecated properties are scheduled for removal or replacement. Continuing to use them means the code will break when the property is removed.
How to fix it #
Use the recommended replacement as indicated in the deprecation notice:
-Foo::$instance;
+Foo::getInstance();
If the calling code is itself deprecated, the error will not be reported. Mark the function or class as deprecated if it is part of a deprecation migration:
+/** @deprecated */
function doFoo(): void
{
Foo::$instance;
}
How to ignore this error #
You can use the identifier staticProperty.deprecated to ignore this error using a comment:
// @phpstan-ignore staticProperty.deprecated
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:
