如何在codeigniter中匹配值时跳过foreach循环

Question

Actually i have three foreach loop.I want to skip the second foreach loop when third foreach loop value($val == $test) match. This is my code.

  <tbody>
   <?php foreach ($tests as $test): ?>
    <tr>
     <td><?= $test; ?></td>
     <?php foreach ($room as $key => $value): ?>
      <?php foreach ($value['dates'] as $val) : ?>
       <?php if ($val == $test) { ?>
        <td><span class="text-danger"><?= $value['room_id'];?</span></td>
       <?php } ?>
      <?php endforeach; ?>
     <td><span class="text-custom"><?= $value['room_id']; ?></span></td>
    <?php endforeach; ?>
   </tr>
 <?php endforeach; ?>
</tbody>

I still maintain you've no need for the third loop. You can remove this and replace it with in_array(), then alter the class name depending on the result.

<tbody>
    <?php foreach ($tests as $test): ?>
    <tr>
        <td><?= $test; ?></td>
        <?php 
          foreach ($room as $key => $value):
              $class = "text-custom";
              if(in_array($test, $value['dates']) {
                  $class = "text-danger";
              }

             <td><span class="<?php echo $class; ?>"><?= $value['room_id'];?</span></td>

         <?php endforeach; ?>
     </tr>
     <?php endforeach; ?>
</tbody> 

Couple of points - you could make this cleaner by using a ternary if statement - and also be careful when using short tags (<?= ?>) as they're not always supported by servers.
