What are some potential pitfalls to avoid when designing a PHP class to handle opening hours data and logic?

One potential pitfall to avoid when designing a PHP class to handle opening hours data and logic is not properly validating input data. It is important to ensure that the input data is in the correct format and follows a consistent structure to avoid errors in the logic of the class. Additionally, it is crucial to handle edge cases such as overlapping opening hours or invalid time ranges to ensure accurate results. 

class OpeningHours {
    private $data;

    public function __construct(array $data) {
        $this->validateInput($data);
        $this->data = $data;
    }

    private function validateInput(array $data) {
        // Validate input data format and structure
        // Handle edge cases such as overlapping opening hours or invalid time ranges
    }
}
