It should multiply each value in the array by this additional argument (‘factor’ inside the function).

For ex: $first = array(5,23,10,8,7). When you say…

$second = multiply($first, 3);
var_dump($second);
this should dump $second which contains [15, 69, 30, 24, 21].

This is my code:

Check example #2 on https://www.php.net/manual/en/functions.arguments.php. See how they use $arg_with_default.
