thinkphp5.0搜索+分页教程,主要是以下这句代码，记录搜索值
->paginate(1,false,$config = ['query'=>array('searchkey'=>$searchkey)]);（记录搜索值）
代码如下：
public function search(){
$where['title'] = array('like','%'.$searchkey.'%');
$result= \think\Db::name('note')->where($where)->paginate(1,false,$config = ['query'=>array('searchkey'=>$searchkey)]);
// halt($_SESSION);
$this->assign('result',$result);
return $this->fetch();
}
public function jg(){
return $this->fetch();
}
