HTML đã tắt, nhưng điều này sẽ giúp bạn bắt đầu:
<?php
$query = 'SELECT CategoryID, CategoryName, ItemID, ItemName
FROM tableName
ORDER BY CategoryID';
$result = mysql_query($query);
if (!$result || mysql_num_rows($result) == 0) {
echo "No rows found";
exit;
}
$lastCatID = 0; //or some other invalid category ID
while ($row = mysql_fetch_assoc($result)) {
if($lastCatID != $row['CategoryID']) {
//starting a new category
if($lastCatID != 0) {
//close up previous table
echo '</table>';
}
//start a new table
echo '<table><th><td colspan="2">Category '
. $row['CategoryName'] .'</td></th>';
$lastCatID = $row['CategoryID'];
}
echo '<tr><td>' . $row['ItemName'] . '</td><td></td></tr>';
}
if($lastCatID != 0) {
//close up the final table
echo '</table>';
}
mysql_free_result($result);
?>
