检查PHP中的最后一条记录

Question

如何实现下面不想显示最后结果的部分？

<?php foreach ($products->result() as $row): ?> 
    <h3><?= $row->header; ?></h3> 
    <p><?= $row->teaser; ?> </p> 
    <a href="">Read More</a>  
    <!-- DONT DISPLAY THIS LAST LINE IF ITS THE LAST RECORD --> 
    <div class="divider"></div> 
<?php endforeach; ?> 

感谢

Answer 1

也许这样吗？

<?php $firstline=true; foreach ($products->result() as $row): ?> 
    <?php if ($firstline) { 
     $firstline=false; 
    } else { 
     echo '<div class="divider"></div>'; 
    }?> 
    <h3><?= $row->header; ?></h3> 
    <p><?= $row->teaser; ?> </p> 
    <a href="">Read More</a> 
<?php endforeach; ?> 

Answer 2

<?php foreach ($products->result() as $row): ?> 
    <h3><?= $row->header; ?></h3> 
    <p><?= $row->teaser; ?> </p> 
    <a href="">Read More</a>  

    <?php if($row!=end($products->result()) 
    <!-- DONT DISPLAY THIS LAST LINE IF ITS THE LAST RECORD --> 
    <div class="divider"></div> 
    <?php } ?> 

<?php endforeach; ?> 

应该这样做

Answer 3

另一种方式来做到这一点：

<?php $results = $products->result(); 
     $count = count($results); 
     $current = 0; 
     foreach ($results as $row): ?> 

    <h3><?= $row->header; ?></h3> 
    <p><?= $row->teaser; ?> </p> 
    <a href="">Read More</a> 

    <?php if (++$current < $count): ?> 
     <div class="divider"></div> 
    <?php endif; ?> 

<?php endforeach; ?> 

从技术上讲，像分隔应该用CSS来实现，使用:first-child和:last-child伪类。但IE不支持:(
