you don't need to, but if you really want to ... echo "<table border=\"0\">\n"; echo "<tr>\n"; $photocount = 0; while($row = mysql_fetch_array($result)) { $smallpic = $row['smallpic']; echo "<td>$smallpic</td>\n"; if (($photocount % 3) == 2) { echo "</tr>\n<tr>\n"; } $photocount++; } // this should add empty cells until the row is complete while ($photocount % 3) { echo("<td></td>"); $photocount++; } echo "</tr>\n"; echo "</table>"; Tim Ward > -----Original Message----- > From: James, Yz [mailto:liljim@btconnect.com] > Sent: 27 February 2001 19:18 > To: php-general@lists.php.net > Subject: while loop and modulus? > > > OK, using this code: > > <? > > echo "<table border=\"0\">\n"; > echo "<tr>\n"; > > $photocount = 0; > > while($row = mysql_fetch_array($result)) { > $smallpic = $row['smallpic']; > > echo "<td>$smallpic</td>\n"; > > if (($photocount % 3) == 2) { > echo "</tr>\n<tr>\n"; > } > $photocount++; > > } > > echo "</tr>\n"; > echo "</table>"; > > ?> > > And 8 photos in the table, I'm getting this output: > > <table border="0"> > <tr> > <td>sm982438092.gif</td> > <td>sm982437452.gif</td> > <td>sm982439016.gif</td> > </tr> > <tr> > <td>sm982529915.gif</td> > <td>sm983222652.gif</td> > <td>sm983222686.gif</td> > </tr> > <tr> > <td>sm983222868.gif</td> > <td>sm983222919.gif</td> > </tr> > </table> > > Great, except it's missing an end cell, and after a few hours > fiddling about > with code last night, I still didn't get any further in > working out how I > was going to echo a table cell even if data's missing.
