我有以下数组：

<?php

$sets = array (
    array (
        'img'        => 'file.png',
        'heading'      => 'Slide Title 1',
        'lead'       => 'Slide leadription 1',

    ),
    array (
        'img'        => 'file.png',
        'heading'      => 'Slide Title 2',
        'lead'       => 'Slide leadription 2',

    ),
    array (
        'img'        => 'file.png',
        'heading'      => 'Slide Title 3',
        'lead'       => 'Slide leadription 2',

    ),
    array (
        'img'        => 'file.png',
        'heading'      => 'Slide Title 3',
        'lead'       => 'Slide leadription 2',

    )

);

?>

的输入。

<?php  
    foreach ($sets as $set) {
?>
    <!-- START THE FEATURETTES -->
    <div class="row featurette">
        <div class="col-md-7">
            <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
            <p class="lead"><?php echo $set['lead']?></p>
        </div>
        <div class="col-md-5">
            <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
        </div>
    </div>

<?php
    }
?>

现在，这是完美的工作，但我希望md-7 HTML和md-5 HTML交替，所以现在每一个其他的将是

<hr class="featurette-divider">
<div class="row featurette">
    <div class="col-md-7">
        <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
    </div>
    <div class="col-md-5">
        <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
        <p class="lead"><?php echo $set['lead']?></p>
    </div>
</div>

所以在图片和细节之间，基本上是左右交替的。

更新

根据Jhansen的建议，这是行不通的。它只需要第一盘，不会在两组之间交替。

<?php 


foreach ($sets as $set) {
?>

      <!-- START THE FEATURETTES -->

          <?php $count = 1; ?>
<?php if( $count % 2 != 0 ): ?>
      <hr class="featurette-divider">

          <div class="row featurette">
            <div class="col-md-7">
              <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
            </div>

            <div class="col-md-5">
              <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
              <p class="lead"><?php echo $set['lead']?></p>
            </div>
</div>

<?php else: ?>

      <hr class="featurette-divider">

          <div class="row featurette">

            <div class="col-md-7">
              <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
              <p class="lead"><?php echo $set['lead']?></p>
            </div>
            <div class="col-md-5">
              <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
            </div>

</div>
<?php endif; ?>`

如果您想切换所有循环，建议的jhansen是正确的：

<?php 
$count=1;
foreach ($sets as $set) { ?>
    <!-- START THE FEATURETTES -->
    <hr class="featurette-divider">
    <div class="row featurette">

        <?php if($count % 2 != 0){ ?>

        <div class="col-md-7">
            <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
        </div>
        <div class="col-md-5">
            <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
            <p class="lead"><?php echo $set['lead']?></p>
        </div>

        <?php }else{ ?>

        <div class="col-md-7">
            <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
            <p class="lead"><?php echo $set['lead']?></p>
        </div>
        <div class="col-md-5">
            <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
        </div>

        <?php } ?>
    </div>
<?php  $count++; } ?>

如果您只想切换第一个，那么应该这样做：

<?php 
foreach ($sets as $k => $set) { ?>
    <!-- START THE FEATURETTES -->
    <hr class="featurette-divider">
    <div class="row featurette">
        <?php if($k==0){ ?>

        <div class="col-md-7">
            <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
        </div>
        <div class="col-md-5">
            <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
            <p class="lead"><?php echo $set['lead']?></p>
        </div>

        <?php }else{ ?>

        <div class="col-md-7">
            <h2 class="featurette-heading"><?php echo $set['heading']?></h2>
            <p class="lead"><?php echo $set['lead']?></p>
        </div>
        <div class="col-md-5">
            <img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
        </div>

        <?php } ?>
    </div>
<?php  } ?>

如果您只是想要替换，为什么不将html封装在一个模数语句中呢？

呃，

<?php $count = 1; ?>
<?php if( $count % 2 != 0 ): ?>
    ... HTML for first arrangement ...
<?php else: ?>
    ... HTML for second arrangement ...
<?php endif; ?>`
