What alternative approaches can be taken to maintain clarity and brevity when implementing functions in a PHP class?

To maintain clarity and brevity when implementing functions in a PHP class, one approach is to follow the Single Responsibility Principle and ensure each function has a clear and specific purpose. Additionally, using meaningful function and variable names, as well as proper commenting, can help improve readability. Lastly, consider breaking down complex functions into smaller, more manageable ones to make the code easier to understand. 

class ExampleClass {
    
    // Function with a clear purpose
    public function calculateTotal($quantity, $price) {
        return $quantity * $price;
    }
    
    // Meaningful function and variable names
    public function getUserInfo($userId) {
        // Code to retrieve user information
    }
    
    // Break down complex functions
    public function processOrder($order) {
        $this->validateOrder($order);
        $this->calculateTotal($order['quantity'], $order['price']);
        $this->sendConfirmationEmail($order['email']);
    }
    
    private function validateOrder($order) {
        // Code to validate order
    }
    
    private function sendConfirmationEmail($email) {
        // Code to send confirmation email
    }
}
