thinkphp5两种分页方法

//法二:使用扩展类库分页

$p->setConfig(\'theme\', $temp_str);
//数据查询
$list = Db::name(\'article\')->order(\'istop desc,addtime desc\')->limit($p->firstRow . \',\' . $p->listRows)->select();
echo Db::name(\'article\')->getLastSql();

//封装变量
$this->assign(\'page\', $page);
$this->assign(\'list\', $list);
// 渲染模板输出
