Error Identifier: staticMethod.deprecatedTrait
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 NewHelper instead */
trait OldHelper
{
public static function compute(): int
{
return 42;
}
}
class MyClass
{
use OldHelper;
}
function doFoo(): void
{
OldHelper::compute();
}
Why is it reported? #
This error is reported by the phpstan-deprecation-rules extension.
A static method is being called on a trait that is marked as @deprecated. Deprecated traits are scheduled for removal or replacement. Calling static methods on them ties the code to an API that will eventually be removed.
How to fix it #
Use the recommended replacement trait or class instead:
<?php declare(strict_types = 1);
function doFoo(): void
{
- OldHelper::compute();
+ NewHelper::compute();
}
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:
<?php declare(strict_types = 1);
+/** @deprecated */
function doFoo(): void
{
OldHelper::compute();
}
How to ignore this error #
You can use the identifier staticMethod.deprecatedTrait to ignore this error using a comment:
// @phpstan-ignore staticMethod.deprecatedTrait
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:
