Array Dinâmico

Galera,

Estou precisando de uma ajuda ao trabalhar com Array Dinâmico. Estou fazendo da seguinte forma:

Loop PHP:

 <?php
 while($totf = $totalf->fetch(PDO::FETCH_ASSOC)) {
 var_dump($totf);
 //}
 ?>
 <tr>
 <td><?php //echo trim($totf['FATURA']); ?></td>
 <td><?php //echo trim($totf['EMISSAO']); ?></td>
 <td><?php //echo trim($totf['CONTATO']); ?></td>
 <td><?php echo trim($totf['Reserva']); ?></td>
 </tr>
 <?php
 }
 ?>

Resultado do SQL:
