How can proper error handling techniques be implemented in PHP classes to provide meaningful feedback to users?

Proper error handling techniques in PHP classes can be implemented by using try-catch blocks to catch exceptions and provide meaningful feedback to users. By throwing custom exceptions with specific error messages, users can easily understand what went wrong in their code. 

class Calculator {
    public function divide($numerator, $denominator) {
        try {
            if ($denominator == 0) {
                throw new Exception("Division by zero is not allowed.");
            }
            return $numerator / $denominator;
        } catch (Exception $e) {
            echo "Error: " . $e->getMessage();
        }
    }
}

$calculator = new Calculator();
echo $calculator->divide(10, 0); // Output: Error: Division by zero is not allowed.
