Why cannot I enter more than 127 items as quantity in the cart. I have tried and changed quantity in carts table from tinyint to smallint and that does not help. The maximum quantity of one item that can be selected is 127.

In the following code, (I know the if statement isn't complete, I am referring to the part before it) I am unclear why (int) is used, after using php for over a year I have never really understood when I should use (int). Is it to make sure the returned number is changed from a decimal to an integer?? Please explain why it is used in this block of code. It is from chapter 6 in the ipn.php script. if (mysqli_num_rows($r) === 0){ $uid = (isset($_POST['custom'])) ? (int) $_POST['custom'] : 0; $status = escape_data($_POST['payment_status'], $dbc); $amount = (int) ($_POST['mc_gross'] * 100); $q = "INSERT INTO orders (user_id, transaction_id, payment_status, payment_amount) VALUES ($uid, '$txn_id', '$status', $amount)"; $r = mysqli_query($dbc, $q); if (mysqli_affected_rows($dbc) === 1){ } }
