对php中的对象的迭代不能正常工作。

Question

我一直在努力让php中的对象数组的迭代工作。我有这样的数组结构：

Array
(

[0] => stdClass Object

(
        [tid] => 7
        [vid] => 2
        [name] => Bakkerijen
        [description] => 
        [format] => full_html
        [weight] => 0
        [depth] => 0
        [parents] => Array
            (
                [0] => 0
            )

    )

[1] => stdClass Object
    (
        [tid] => 10
        [vid] => 2
        [name] => Horeca
        [description] => 
        [format] => full_html
        [weight] => 1
        [depth] => 0
        [parents] => Array
            (
                [0] => 0
            )

    )

[2] => stdClass Object
    (
        [tid] => 8
        [vid] => 2
        [name] => Food Shops
        [description] => 
        [format] => full_html
        [weight] => 2
        [depth] => 0
        [parents] => Array
            (
                [0] => 0
            )

    )   

)

如果一个值与这个数组中的tid匹配，我想向li添加一个选定的类。

下面是我所做的代码和HTML：

 <?php $current_tid = 7; ?>
 <?php foreach ($terms as $term): ?>
              <?php unset($term->parents); ?> 
                <?php if($term->tid == $current_tid) { ?>
                <li><a href="/portfolio#filter=.tid-<?php print $term->tid; ?>" class="selected"><?php print $term->name;?></li>
                <?php }else if($term->tid != $current_tid){ ?>
                <li><a href="/portfolio#filter=.tid-<?php print $term->tid; ?>"><?php print $term->name; ?></a></li>

                <?php } ?>
              <?php endforeach; ?> 

这是我得到的最后一个输出：

<ul class="cathome-list-inner">                            
<li>
    <a class="selected" href="/portfolio#filter=.tid-7">Bakkerijen</a>
</li>
<a class="selected" href="/portfolio#filter=.tid-7"></a>
<li>
    <a class="selected" href="/portfolio#filter=.tid-7"></a>
    <a href="/portfolio#filter=.tid-10">Horeca</a>
</li>                                          
<li>
    <a href="/portfolio#filter=.tid-8">Food Shops</a></li>
<li>
    <a href="/portfolio#filter=.tid-9">Non-food Shops</a></li>
<li>
    <a href="/portfolio#filter=.tid-11">Privé interieurprojecten</a>
</li>

问题是为什么我要在所选的类中添加额外的锚标记。

在这条线上：

<li><a href="/portfolio#filter=.tid-<?php print $term->tid; ?>" class="selected"><?php print $term->name;?></li>
