<br>
下面来介绍用法：<br>
$Configuration = array(<br>
'total' => 30, //总条数<br>
'traction' => 3, //当前页面需要显示的条数<br>
'url' => './StudentManagement', //分页按钮的url地址<br>
);<br>
//调用分页模块，第一个参数是将页面获取的数据传递进去，$_REQUEST全局变量，POST或者GET的都可以获取大。第二个参数就是上面的数组，配置参数<br>
$PageingObj = new PagingModel($_REQUEST, $Configuration);<br>
$this->assign('pageing', $PageingObj->GetPagingHtmlInfo()); //然后就调用这个方法返回分页代码，放在页面上去就可以了
