You should always separate data manipulations from output.
Select your data first:
$db_res = mysqli_query( $db_link, $sql );
$data = array();
while ($row = mysqli_fetch_assoc($db_res))
{
$data[] = $row;
}
Note that since PHP 5.3 you can use fetch_all()
instead of the explicit loop:
$db_res = mysqli_query( $db_link, $sql );
$data = $db_res->fetch_all(MYSQLI_ASSOC);
Then use it as many times as you wish:
//Top row
foreach ($data as $row)
{
echo "<td>". $row['Title'] . "</td>";
}
//leftmost column
foreach ($data as $row)
{
echo "<tr>";
echo "<td>". $row['Title'] . "</td>";
.....
echo "</tr>";
}
