What potential pitfalls should be considered when using Traits in PHP for code reusability and maintainability?

One potential pitfall when using Traits in PHP for code reusability and maintainability is the risk of creating a complex and tangled class hierarchy, leading to difficulties in understanding and maintaining the code. To mitigate this, it is important to carefully plan the use of Traits and avoid excessive nesting or overlapping of Traits.

// Example of using Traits with caution to avoid complex class hierarchy
trait Logging {
    public function log($message) {
        echo $message;
    }
}

trait Validation {
    public function validateInput($input) {
        // validation logic
    }
}

class User {
    use Logging, Validation;
    
    // class implementation
}
