DeprecatedTrait

A trait annotated with @deprecated is being used via a use statement. Deprecated traits are scheduled for removal and should not be used in new code.

Example

<?php
/**
 * @deprecated Use the new LoggingTrait instead.
 */
trait OldLoggingTrait {
    public function log(string $msg): void {}
}

class MyClass {
    use OldLoggingTrait; // uses deprecated trait
}

How to fix

Replace the deprecated trait with its documented successor.
