贴一个在用的codeigniter分页类
贴自己自己正在使用的codeigniter中的分页类。供大家参考下。也谢谢这个类的书写者。因为您的分享，所以让大家得到了便捷。先贴出来这个分页类：

大家可以在相应的控制器中写下具体配置：
$page_config['perpage']=5; //每页条数$page_config['part']=2;//当前页前后链接数量$page_config['url']='vote/getview';//url$page_config['seg']=3;//参数取 index.php之后的段数，默认为3，即index.php/control/function/18 这种形式$page_config['nowindex']=$this->uri->segment($page_config['seg']) ? $this->uri->segment($page_config['seg']):1;//当前页$this->load->library('mypage_class');$countnum=100;//得到记录总数--应该是调用model中的某方法得来的。这里省略。$page_config['total']=$countnum;$this->mypage_class->initialize($page_config);$this->load->view('template/replist');
视图里code：
<div class="page"> <span style="white-space: pre;" mce_style="white-space: pre;"></span><?php echo $this->mypage_class->show(1); ?></div>
