Use cache with an expiration date of 2225 If you want to update your css file, use a new filename like css_file_v2.css

Thanks!

Sorry, I am still receiving the same error

Fatal error: func_get_args(): Can't be used as a function parameter in MathClass.php on line 6

What is the solution?

Hi there, I am starting to learn OO PHP programming. After running math.php, it gives an output 'Use only numbers'. Why? I don't understand this. math.php <?php require('MathClass.php'); $c = new MathClass(); echo $c->add(5,10,15,20); ?> MathClass.php <?php class MathClass{ function add(){ $args = func_num_args(); $sum = 0; $i = 0; for ($i ; $i < $args ; $i++){ is_int(func_get_args($i)) ? $sum += func_get_args($i) : die('Use only numbers'); } return $sum; } } ?>
