一、前后端分页1.控制器示例：$news=Db::name('news')->where("type",$type)->paginate(4,false,['query'=>$this->request->param()]);$page=$news->render();//渲染$this->assign('news',$news);//赋值$this->assign('page',$page);//赋值2.页面渲染{$page}**注意点：**（1）带分类idpaginate(4,false,['query'=>$this->request->param()]);（2）不带分类idpaginate(4);二、PHP后端分页1.$page=0;$size=10;$pnum=ceil(count($results)/$size);$newArray=array_slice($results,($page-1)*$size,$size);2.$results=Db::name('test')->where($where)->page($page,6)->select();
