Error Identifier: sealed.deprecatedTrait

← Back to sealed.*

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 NewTrait instead */
trait DeprecatedTrait {}

/**
 * @phpstan-sealed DeprecatedTrait
 */
class Foo
{
}

Why is it reported? #

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

The @phpstan-sealed PHPDoc tag references a trait that has been marked as @deprecated. Deprecated traits are planned for removal in a future version, and sealed constraints should not depend on them.

How to fix it #

Replace the deprecated trait reference with its non-deprecated replacement:

 /**
- * @phpstan-sealed DeprecatedTrait
+ * @phpstan-sealed NewTrait
  */
 class Foo
 {
 }

How to ignore this error #

You can use the identifier sealed.deprecatedTrait to ignore this error using a comment:

// @phpstan-ignore sealed.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:

parameters:
	ignoreErrors:
		-
			identifier: sealed.deprecatedTrait
