大家好，我是 php 世界的新手，还在学习，我完全迷路了。我已经尝试了一切并阅读了很多博客，但没有什么能帮助我弄清楚如何去做。我有这段代码（下面），它工作得很好..它把一个长列表分成 5 个元素的块，这要归功于<ul>& <li>。

<?php
$values = range(1, 31);
$rows = array_chunk($values, 5);


foreach ($rows as $row) {
    print "<ul>";
    foreach ($row as $value) {
        print "<li>" . $value . "</li>";
    }
    print "</ul>";
}
?>

但是当我尝试将它与我的其他代码（如下）合并时，它停止工作。它只显示<ul>'s，没有数据放入<li>'s甚至不显示。

<?php 
        $product = Mage::getModel('catalog/product');
        $attributes = Mage::getResourceModel('eav/entity_attribute_collection')
        ->setEntityTypeFilter($product->getResource()->getTypeId())
        ->addFieldToFilter('attribute_code', 'manufacturer');
        $attribute = $attributes->getFirstItem()->setEntity($product->getResource());
        $manufacturers = $attribute->getSource()->getAllOptions(false);
?>


<ul> 
<?php foreach ($manufacturers as $manufacturer): ?>
    <li>
        <a href="/manufacturer/<?php echo $manufacturer['label'] ?>">
            <?php echo $manufacturer['label'] ?>
        </a>
    </li>
<?php endforeach; ?>
</ul>

这是我尝试过的变体之一（没有显示 500 错误的变体）

<?php
$rows = array_chunk($manufacturers, 5);


foreach ($manufacturers as $manufacturer) {
    echo "<ul>";
    foreach ($row as $manufacturer) {
        echo "<li>"  ?> 
                <a href="/manufacturer/<?php echo $manufacturer['label'] ?>"><?php echo $manufacturer['label'] ?></a>
<?php   echo "</li>"; ?>
<?php    }
    echo "</ul>";
}
?>

我可能知道我正在做的事情是完全错误的，但正如我所说，我还是新手（我知道我还有很长的路要走。）

任何帮助都将不胜感激。先感谢您！

你混合你的变量。可能你想要这样的东西：

<?php
$rows = array_chunk($manufacturers, 5);

foreach ($rows as $row) {
?>
    <ul>
    <?php foreach ($row as $manufacturer) { ?>
        <li>
            <a href="/manufacturer/<?php echo $manufacturer['label']; ?>">
                this is a link
            </a>
        </li>
    <?php } ?>
    </ul>
<?php } ?>

请注意变量是如何在两个 foreach 循环中级联的。
