Note Submitter: keith@keithtyler.com ---- It looks like the reason for the double vision is so that when you want to use the sql results, you can call the array elements via either indices (e.g. $line[0], $line[1], etc.) or by their database field names (e.g. $line["uid"], $line["pw"], $line["gid"], etc.). You can see this by changing the example to print $col_name as well as $col_value. Each repeated val shows up with a different key (of course) each time.
