How can PHP classes be structured to ensure clean and efficient data handling from form submissions?

To ensure clean and efficient data handling from form submissions in PHP classes, you can create a separate class specifically for handling form data. This class can have methods for validating, sanitizing, and processing the form data before storing it in the database or performing any other actions. By encapsulating the form handling logic within a dedicated class, you can keep your code organized, reusable, and easier to maintain. 

class FormHandler {
    public function sanitizeInput($input) {
        // Sanitize input data here
        return $sanitizedInput;
    }

    public function validateInput($input) {
        // Validate input data here
        return $isValid;
    }

    public function processForm($formData) {
        $sanitizedData = $this->sanitizeInput($formData);
        
        if ($this->validateInput($sanitizedData)) {
            // Process the form data and perform necessary actions
        } else {
            // Handle invalid input
        }
    }
}

// Implementation example
$formHandler = new FormHandler();
$formData = $_POST; // Assuming form data is submitted via POST method
$formHandler->processForm($formData);
