下面提供一个PHP的无限分级类代码，想要实现无限分级类的朋友们可以试试。Bug已经检查修正过，直接复制代码就能使用尖括号需要替换一下）。

1、数据库ProductShow中有b_mtype表，建表语句如下：

<ol class="dp-sql">
<li class="alt"><span><span class="keyword">CREATE</span><span> </span><span class="keyword">TABLE</span><span> `b_mtype` (  </span></span></li>

</li>
<li class="alt">

<li class="">
<span>  </span><span class="keyword">PRIMARY</span><span> </span><span class="keyword">KEY</span><span>  (`typeid`)  </span>
</li>
<li class="alt"><span>) TYPE=MyISAM;  </span></li>
<li class=""><span> </span></li>
</ol>
