Garry,
You can't do it with a loop. You'll have to fetch a single row each time.
You could do it something like:
$last = 0;
$result = mysql_query("SELECT * FROM myTable WHERE id > $last ORDER BY id
LIMIT 1");
if ($result) { // Ensure it worked
if (mysql_num_rows() > 0) { // And returned data
$data = mysql_fetch_array($result);
// Process the row
$last = $data['id'];
}
else {
// End of data
}
}
else {
// Process the mysql error
}
Assuming id is a unique integer > 0 (or at least unique within other WHERE
clause settings).
