用ThinkPHP的标签做网站觉得不够快速，就自己写了一个扩展，感觉挺好的，分享出来，给有需要的TPER。

DEMO：
文件放在ThinkPHPExtendDriverTagLib下，然后在config.php文件中引入，‘TAGLIB_PRE_LOAD‘ => ‘EP‘,
table:表名，where查询条件，order排序，id结果变量，page分页开启，field字段，key循环变量，mod取模,debug是否调试

1. <EP:select sql="select * from table order by id desc" limit="10" page="1"></EP:select>
2. <EP:select table="article" limit="10"></EP:select>

复制代码

无论是频道页面还是列表页面都可以实现分页了。

1. <div id="pages">{$pages}</div>
