PHP creating an array from form input fields

Question

I'm trying to create an array to store numbers and add them together.

<input type="number" name="numbers[]"/>

I'm getting an undefined variable on the following line

foreach($numbers as $number)

I'm sure this is probably something basic but I'm relatively new to php and help would be greatly appreciated.

If you posted the inputs you're showing from one page to another and you need to run through the list you should set it up like this:

if (isset($_REQUEST['numbers']) && is_array($_REQUEST['numbers'])) {
  $numbers = $_REQUEST['numbers'];

  foreach ($numbers as $number) {
    print $number;
  }
}
