php - 将 foreach 循环限制为第一个数组

Question

这是我的代码:

<?php
         foreach ($productsRecord['images'] as $upload):?>
          <?php if ($upload['hasThumbnail']): ?>
            <a href="<?php echo $upload['urlPath'] ?>" rel="lightbox" class="imgborder" title="<?php echo $productsRecord['name'] ?>"><img src="<?php echo $upload['urlPath'] ?>"  alt="" /></a><br />



          <?php endif ?>
        <?php endforeach ?>

我如何将结果限制为仅第一个结果，我会使用 break 吗？声明？

干杯

Answer 1

尝试使用current()

你的代码应该是这样的:

<?php reset($productsRecord['images']); ?>
<?php $upload = current($productsRecord['images']);?>
<?php if ($upload['hasThumbnail']): ?>
    <a href="<?php echo $upload['urlPath'] ?>" rel="lightbox" class="imgborder" title="<?php echo $productsRecord['name'] ?>"><img src="<?php echo $upload['urlPath'] ?>"  alt="" /></a><br />
<?php endif ?>
