Error Identifier: property.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 */
class Helper
{
public int $value = 0;
}
class Service
{
/** @var Helper */
public $helper;
}
Why is it reported? #
The property’s native type declaration references a deprecated trait (or class that is actually a trait). Continuing to use deprecated types couples code to APIs that are planned for removal.
This also triggers when accessing a property of an object whose declaring class is deprecated.
How to fix it #
Replace the deprecated type with its recommended replacement:
class Service
{
- /** @var Helper */
- public $helper;
+ /** @var NewHelper */
+ public $helper;
}
How to ignore this error #
You can use the identifier property.deprecatedTrait to ignore this error using a comment:
// @phpstan-ignore property.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:
