调用的方法

如果是用这样的一个模板
<table>
<!-- BEGIN list -->
<tr>
<td>{var0}</td>
<td>{var1}</td>
</tr>
<!-- END list -->
</table>
<table>
<!-- BEGIN list2 -->
<tr>
<td>{var0}</td>
<td>{var1}</td>
</tr>
<!-- END list2 -->
</table>
则这样用
<?

include('template.h.php');
$data=array();
$data['list']=array(
'0'=>array('a1','a2'),
'1'=>array('b1','b2') <#006600>1 undefined -->", $str);

其它的方法大家再研究一下吧。如果有兴趣的话，可以帮我扩充一下。呵呵
