Thanks for reminding me about arrays. > (You must be quite adept at arrays. ) I don't know, but I often stuff things into array, such as the following snippet: ... while ($r = mysql_fetch_row ($res)) { $news_paged[$page][$r[0]]['short_desc'] = $r[1]; if (isset ($r[2])) $news_paged[$page][$r[0]]['long_desc'] = $r[2]; ... I wonder if there's a noticable difference in performance between variable variables and arrays...

I'm a total newbie when it comes to SQL beyond simple SELECTs. If there's a noticable gain to be made from limiting the number of rows returned from the database, then that is probably worth persuing. Otherwise, I'd do it in PHP. /Nisse
