Question

我的数据库中有一个包含类似数据的表，但其他数据包含更多数据。

我想要的是通过循环回显数据。我的问题是我想从2到2获取数据。我正常显示数据的代码是

<?php $count = $helper->count('testimony');?>
  <div class="owl-4">
    <?php for ($i=0; $i < $count; $i++) : ?>
      <div class="item">
      <?php echo '<h3>'.$helper->get('authorname', $i).'</h3>';
            echo '<p>'.$helper->get('testimony', $i).'</p>' ;?>
      </div>
    <?php endfor; ?>
  </div>

返回

<div class="owl-4">
    <div class="item">
        <h3>Author 1</h3>
        <p>Testimony 1</p>
    </div>
    <div class="item">
        <h3>Author 2</h3>
        <p>Testimony 2</p>
    </div>
    ................
</div>

我如何转过来给我这个

<div class="owl-4">
    <div class="item">
        <h3>Author 1</h3>
        <p>Testimony 1</p>

        <h3>Author 2</h3>
        <p>Testimony 2</p>
    </div>
    <div class="item">
        <h3>Author 3</h3>
        <p>Testimony 3</p>

        <h3>Author 4</h3>
        <p>Testimony 4</p>
    </div>
    ................
</div>

感谢

Answer 1

您可以每两次迭代显示<div class="item">和</div>，例如检查$i是否为偶数：

<?php $count = $helper->count('testimony');?>
<div class="owl-4">
<?php for ($i=0; $i < $count; $i++) : ?>
  <?php if ($i%2==0): ?>
     <div class="item">
  <?php endif; ?>
  <?php echo '<h3>'.$helper->get('authorname', $i).'</h3>';
        echo '<p>'.$helper->get('testimony', $i).'</p>' ;?>
  <?php if ($i%2==0): ?>
     </div>
  <?php endif; ?>
<?php endfor; ?>

只需将计数器增加2而不是每次增加1。

<div class="panel panel-default">
                <div class="panel-body">This page is temporarily disabled by the site administrator for some reason.</div> 
                <div class="panel-footer clearfix">
