        <?php
        trait TraitA {
            public function methodA() {
                return "Method A";

            public function methodB() {
                return "Method B";
            }

            use TraitA, TraitB;

            public function getDescription() {
                return $this->methodA() . " and " . $this->methodB();
            }
        }

        function deepCopyTraits($object) {
            $reflectionClass = new ReflectionClass($object);
            $clone = $reflectionClass->newInstanceWithoutConstructor();

            foreach ($reflectionClass->getTraits() as $trait) {
                $traitProperties = $trait->getProperties();
                foreach ($traitProperties as $property) {
                    $propertyName = $property->getName();
                    $property->setAccessible(true);
                    $copyProperty = $property->getValue($object);
                    $property->setValue($clone, $copyProperty);
                }
            }
            return $clone;
        }

        // Example usage
        $original = new BaseClass();
        $copy = deepCopyTraits($original);
        echo $copy->getDescription();
        ?>
