CF. DomainException  : "DomainException corresponds to RangeException and we should use them in simillar situations.  But first exception is designed to use when we are sure the problem is with our project, third-part elements etc. (simply: logical error), the second way is designed to use when we are sure the problem is with input data or environment (simply: runtime error)."

function divide($divident, $input) {
    if(!is_numeric($divident) || !is_numeric($input)) {
        throw new InvalidArgumentException("Function accepts only numeric values");
    }
    if($input == 0) {
        throw new RangeException("Divisor must not be zero");
    }
    return $divident / $input;
}
