Here's an example I use when the returned data set is an unknown
number of records. It takes care of the math for having equal items
in as many columns. Example is for MySQL, but logic is same. Sorry
if too confusing... it might help...
If you're not worried about each item being in its own cell, it works
great...
<?
echo "<table>\n<tr>\n<td>";
$stateCount = 1;
$col1 = round($nStates / 3); // $nStates = number of states returned
in a region
$col2 = round(($nStates / 3) + $col1);
while ($state = mysql_fetch_object($rStates)) {
$stURL = str_replace (" ","+", $state->stateName);
echo "<a href=\"" . $httpPath . $locDir['states'] . $stURL . ".html
\" title=\"" . $state->linkTitle . "\">" . $state->stateName . "</
a><br />\n";
if ($stateCount == $col1) {
echo "</td>\n<td>\n";
}
if ($stateCount == $col2) {
echo "</td>\n<td>\n";
}
$stateCount++;
}
echo "</td>\n</tr>\n</table>\n";
?>
