PHP Array对HTML的层次结构（多面包屑路径）

Question

我在PHP中的数组做的print_r（$面包屑）

Array (
    [url] => /category/ 
    [text] => Category 
) 
Array (
    [url] => /category/subcategory/ 
    [text] => Subcategory 
) 
Array (
    [url] => /category/subcategory/subsubcategory/ 
    [text] => Subsubcategory 
) 

我想这个面包屑显示当看起来像这样

Category > Subcategory > Subsubcategory 

据Google docs的HTML应该是这样的：

<div xmlns:v="http://rdf.data-vocabulary.org/#"> 
    <span typeof="v:Breadcrumb"> 
    <a href="/category/" rel="v:url" property="v:title"> 
     Category 
    </a> › 
    <span rel="v:child"> 
     <span typeof="v:Breadcrumb"> 
     <a href="/category/subcategory/" rel="v:url" property="v:title"> 
      Subcategory 
     </a> › 
     <span rel="v:child">   
      <span typeof="v:Breadcrumb"> 
      <a href="/category/subcategory/subsubcategory/" rel="v:url" property="v:title"> 
       Subsubcategory 
      </a> ›   
      </span> 
     </span> 
     </span> 
    </span> 
    </span> 
</div> 

如何从PHP数组去到HTML？

我已经看了other answers，但他们没有我的情况下工作

这是我怎么会去这样的：

的PHP：

<?php 
    $breadcrumb = array(
     array(
      'url' => '/category/', 
      'text' => 'Category' 
     ), 
     array(
      'url' => '/category/subcategory/', 
      'text' => 'Subcategory' 
     ), 
     array(
      'url' => '/category/subcategory/subcategory', 
      'text' => 'Subsubcategory' 
     ) 
    ); 
    $children = count($breadcrumb) - 1; 
?> 

显示标记：

<div xmlns:v="http://rdf.data-vocabulary.org/#"> 
    <span typeof="v:Breadcrumb"> 
     <?php for ($i = 0; $i < count($breadcrumb); $i++) : ?> 
     <?php if ($i == 0) : ?> 
     <a href="<?php echo $breadcrumb[0]['url']; ?>" rel="v:url" property="v:title"><?php echo $breadcrumb[0]['text']; ?></a> › 
     <?php else : ?> 
     <span rel="v:child"> 
      <span typeof="v:Breadcrumb"> 
       <a href="<?php echo $breadcrumb[$i]['url']; ?>" rel="v:url" property="v:title"><?php echo $breadcrumb[$i]['text']; ?></a> › 
     <?php endif; ?> 
     <?php endfor; ?> 
     <?php echo str_repeat("</span>\r\n</span>\r\n", $children); ?> 
    </span> 
</div> 

如果需要，这种方法还可以允许更深的子类别。

希望它可以帮助

更新显示代码：

<div xmlns:v="http://rdf.data-vocabulary.org/#"> 
    <span typeof="v:Breadcrumb"> 
     <?php for ($i = 0; $i < count($breadcrumb); $i++) : ?> 
     <?php if ($i == 0) : ?> 
     <a href="<?php echo $breadcrumb[0]['url']; ?>" rel="v:url" property="v:title"><?php echo $breadcrumb[0]['text']; ?></a> › 
     <?php else : ?> 
     <span rel="v:child"> 
      <span typeof="v:Breadcrumb"> 
       <a href="<?php echo $breadcrumb[$i]['url']; ?>" rel="v:url" property="v:title"><?php echo $breadcrumb[$i]['text']; ?></a><?php if ($i < $children):?> › <?php endif; ?> 
     <?php endif; ?> 
     <?php endfor; ?> 
     <?php echo str_repeat("</span>\r\n</span>\r\n", $children); ?> 
    </span> 
</div> 

上面的代码从修剪结束的最后>符号:)
