how to show last row of SQL query result in (php) <tfoot> and exclude in <tbody>? - php

Question

My database colleague built a couple of views and SP's for me so I can focus on html/php.
One is a query that shows a "total" row at the bottom of the table.
I want to:
Exclude this last row on my <tbody>
Show this single row in my <tfoot>
Why don't I just show everything in <tbody> since the totals row will always show at the bottom anyway? Because I want my <tfoot>'s <td>'s colspan to be different, for presentation purposes.
How can I do this using php alone?
I'm using basic PDO:
foreach($table as $row) {
echo '<tr>
<td>'.$row['Item'].'</td>
<td>'.$row['Amount'].'</td>
</tr>';
}

Answer 1

This should work as long as the last row is not exactly the same as any other row.
$last_row = end($table);
echo '<tbody>';
foreach ($table as $row) {
if ($row === $last_row) continue;
echo '<tr>
<td>'.$row['Item'].'</td>
<td>'.$row['Amount'].'</td>
</tr>';
}
echo '</tbody>';
echo '<tfoot>
<tr>
<td>'.$last_row['Item'].'</td>
<td>'.$last_row['Amount'].'</td>
</tr>
</tfoot>';
If it's possible that the last row is not unique you can use the key instead:
$last_key = count($table) - 1;
echo '<tbody>';
foreach ($table as $key => $row) {
if ($key === $last_key) continue;
echo '<tr>
<td>'.$row['Item'].'</td>
<td>'.$row['Amount'].'</td>
</tr>';
}
echo '</tbody>';
echo '<tfoot>
<tr>
<td>'.$table[$last_key]['Item'].'</td>
<td>'.$table[$last_key]['Amount'].'</td>
</tr>
</tfoot>';

Answer 2

$total = 0;
foreach($table as $row) {
$total += $row['Amount'];
echo '<tr>
<td>'.$row['Item'].'</td>
<td>'.$row['Amount'].'</td>
</tr>';
}
echo '<tr>
<td>Total:</td>
<td>'.$total.'</td>
</tr>';
You don't need to use thead or tfoot if you do not intend to use them to style your content or in some cases SEO purposes.
