Using loops to implement PHP classification lists_PHP tutorial

html code... uses two foreach loops

1. < div class="modContent"> 
2. < %foreach from=$sort item=s%> 
3. < div class="categories"> 
4. < acronym class="icon">< /acronym>
5. < a href="category.php?sort_id=
   < %$s.sort_id%>">
6. < strong>< %$s.sort_name%>< /strong>
7. < /a>< br /> 
8. < %foreach from=$s.zi item=z%> 
9. < a href="category.php?sort_id=
   < %$z.sort_id%>" 
10. title="< %$z.sort_name%>">
11. < %$z.sort_name%>
12. < /a>    
13. < %/foreach%> 
14. < /div>   
15. < %/foreach%> 
16. < /div> 

PHP分类列表之PHP代码 简单的说就是利用foreach 循环一个数组然后在这个数组里插入一个索引 索引对的直就是每次查询的所有子分类

<ol class="dp-xml">
<li class="alt"><span><span>//商品分类  </span></span></li>
<li>
<span>$</span><span class="attribute">sql</span><span>=</span><span class="attribute-value">"SELECT * FROM `hcl_sort` <br>WHERE `parent_id`=0 ORDER BY <br>`sort_id` DESC"</span><span>;  </span>
</li>
<li class="alt">
<span>$</span><span class="attribute">sort</span><span>=$db-</span><span class="tag">></span><span>getAll($sql);  </span>
</li>
<li>
<span>foreach ($sort as $</span><span class="attribute">key</span><span>=</span><span class="tag">></span><span>$val){  </span>
</li>
<li class="alt">
<span>$</span><span class="attribute">sort_id</span><span>=$sort[$key]['sort_id'];  </span>
</li>
<li>
<span>$</span><span class="attribute">sql</span><span>=</span><span class="attribute-value">"SELECT * FROM `hcl_sort`<br> WHERE `parent_id`={$sort_id}"</span><span>;  </span>
</li>
<li class="alt">
<span>$</span><span class="attribute">zi</span><span>=$db-</span><span class="tag">></span><span>getAll($sql);  </span>
</li>
<li><span>$sort[$key]['zi']=$zi;  </span></li>
<li class="alt"><span>}  </span></li>
<li>
<span>$tpl-</span><span class="tag">></span><span>assign('sort',$sort); </span>
</li>
</ol>

以上代码就是PHP分类列表的具体解决方法。
