Moving through a table with gaps

I'm wondering what the best way is to move through a  mySql table that has  primary index gaps.  For example, someone may have gone through the table and removed duplicate records, so now the primary index runs 1, 2, 4, 5, 6, 9. . .

I want to do something like below:

for($i=1; $i<=$maxId; $i++) {
	$query = "SELECT email FROM sales WHERE orderID = $i";
	$result = mysqli_query($db, $query) or die ("Couldn't read email from sales table at orderID = $i" . mysqli_error($db));
	$row = mysqli_fetch_assoc($result);
	$email = $row['email'];

But I don't want to fall into the "die" hole every time a record is missing.

Thanks for any ideas...
