Hey everyone. Here is my code.

<table border="1" style="width:800px">
                <?php $schedule_db = mysql_query("SELECT * FROM schedule WHERE '00:00' is not null and '01:00' is not null and '02:00' is not null and '03:00' is not null and '04:00' is not null and '05:00' is not null and '06:00' is not null and '07:00' is not null and '08:00' is not null and '09:00' is not null and '10:00' is not null and '11:00' is not null and '12:00' is not null and '13:00' is not null and '14:00' is not null and '15:00' is not null and '16:00' is not null and '17:00' is not null and '18:00' is not null and '19:00' is not null and '20:00' is not null and '21:00' is not null and '22:00' is not null and '23:00' is not null") 
                or die(mysql_error()); ?>
                <form method="post" action="config_action.php">
                <?php while($schedule = mysql_fetch_array( $schedule_db )) { ?>
                    <tr><?php if(isset($schedule['00:00'])) { ?><td style="width:32px"><?php echo $schedule['00:00'] ?></td><?php } if(isset($schedule['02:00'])) { ?><td style="width:32px"><?php echo $schedule['02:00'] ?></td><?php } if(isset($schedule['03:00'])) { ?><td style="width:32px"><?php echo $schedule['03:00'] ?></td><?php } if(isset($schedule['04:00'])) { ?><td style="width:32px"><?php echo $schedule['04:00'] ?></td><?php } if(isset($schedule['05:00'])) { ?><td style="width:32px"><?php echo $schedule['05:00'] ?></td><?php } if(isset($schedule['06:00'])) { ?><td style="width:32px"><?php echo $schedule['06:00'] ?></td><?php } if(isset($schedule['07:00'])) { ?><td style="width:32px"><?php echo $schedule['07:00'] ?></td><?php } if(isset($schedule['08:00'])) { ?><td style="width:32px"><?php echo $schedule['08:00'] ?></td><?php } if(isset($schedule['09:00'])) { ?><td style="width:32px"><?php echo $schedule['09:00'] ?></td><?php } if(isset($schedule['10:00'])) { ?><td style="width:32px"><?php echo $schedule['10:00'] ?></td><?php } if(isset($schedule['11:00'])) { ?><td style="width:32px"><?php echo $schedule['11:00'] ?></td><?php } if(isset($schedule['12:00'])) { ?><td style="width:32px"><?php echo $schedule['12:00'] ?></td><?php } if(isset($schedule['13:00'])) { ?><td style="width:32px"><?php echo $schedule['13:00'] ?></td><?php } if(isset($schedule['14:00'])) { ?><td style="width:32px"><?php echo $schedule['14:00'] ?></td><?php } if(isset($schedule['15:00'])) { ?><td style="width:32px"><?php echo $schedule['15:00'] ?></td><?php } if(isset($schedule['16:00'])) { ?><td style="width:32px"><?php echo $schedule['16:00'] ?></td><?php } if(isset($schedule['17:00'])) { ?><td style="width:32px"><?php echo $schedule['18:00'] ?></td><?php } if(isset($schedule['19:00'])) { ?><td style="width:32px"><?php echo $schedule['19:00'] ?></td><?php } if(isset($schedule['20:00'])) { ?><td style="width:32px"><?php echo $schedule['20:00'] ?></td><?php } if(isset($schedule['21:00'])) { ?><td style="width:32px"><?php echo $schedule['21:00'] ?></td><?php } if(isset($schedule['22:00'])) { ?><td style="width:32px"><?php echo $schedule['22:00'] ?></td><?php } if(isset($schedule['23:00'])) { ?><td style="width:32px"><?php echo $schedule['23:00'] ?></td><?php } ?></tr>
                <?php } ?>
                </form>
</table>

Ne yapmak istediğinizi bir sütununda bir değer bulunması halinde her bir sütun ama ne zaman gösteren bir tablo başlığı (tüm diğer satır yukarıda sadece bir satır) var.

Ben böyle bir şey için ben kod düşündüm:

<tr><?php if(isset($schedule['00:00'])) { ?><td style="width:32px">00:00</td><?php } if(isset($schedule['01:00'])) { ?><td style="width:32px">01:00</td><?php } ?> etc.

Bir süre döngü içinde olduğu ancak, çünkü ben sadece üstünde bir kez gerçekleşmesi istiyorum, ne istediğinizi, hangi değil her gerçek satırda önce olacaktır.

Bu sorunu nasıl çözebilirim? Bir keresinde sadece döngü yapmak için bu eklenecek bir şey var mı?

Teşekkürler!
