这段代码怎么判断？

[h123hu]

以下代码，有的里面有链接，有的没有
不能用JS来判断，
请问如何用PHP来判断有链接的分别是哪几个？


<table class="__01" width="990" height="759" border="0" cellpadding="0" cellspacing="0">

<tr>

<td>

<a href="#" target="_blank"><img src="images/selfJSbaobei_01.gif" width="243" height="379" alt=""></a></td>

<td>

<img src="images/selfJSbaobei_02.gif" width="252" height="379" alt=""></td>

<td>

<img src="images/selfJSbaobei_03.gif" width="251" height="379" alt=""></td>

<td>

<a href="#" target="_blank"><img src="images/selfJSbaobei_04.gif" width="244" height="379" alt=""></a></td>

</tr>

<tr>

<td>

<a href="#" target="_blank"><img src="images/selfJSbaobei_06.gif" width="252" height="380" alt=""></a></td>

用php

把td 存到数据库、文件或数组里
遍历
