Answer 1

Nothing much to explain here. if you want to store multiple array inside of array to store multiple file names. I assume that $files is a single file name only. Try this.

$_SESSION['cart'] = array(
    array(
        'id'=>$productid, 
        'quantity'=>$quantity, 
        'detail'=>$detail, 
        'files'=>$files
    )
);
