How do I save every option of a select box in an array? (PHP) [closed]

-2

Let's say I have an select box: <select name="cart" id="cart" size="5"></select>

This box is filled with 5 different options.
If I write $data = $_POST['cart']; it will only save the option, which is currently selected. How can I save every option (so the ones which are not selected as well)?

You can't get the unselected value from $_POST, but you can do as follows

$allOption = [

    1,2,3,4,5

];

$selected = $_POST['cart'];

$unselected = array_diff($allOption, $selected);
