Lest not touch the validation topic - it's obvious and we are not
talking about it.
As for the DB - I don't want to write code like this.
// Select from DB
// Start the loop fetch the data
settype('integer', $row['id']);
settype('float', $row['price']);
settype('int', $row['amount']);
settype('integer', $row['order_id']);
// ....
// End of loop here
// Do the data processing
Sorry, but that's just stupid code.
