thinkphp6 另一种where判断写法

记录一下这种判断写法

        $sqlModel = Db::name('news');
        $sqlModel = $sqlModel->where('endtime','>=',time());
        $sqlModel = $sqlModel->where('begintime','<=',time());
        $sqlModel = $sqlModel->where('endtime','>=',time());$sqlModel = $sqlModel->whereRaw("FIND_IN_SET('{$companyinfo['tradeid']}', tradeid)");
        $sqlModel = $sqlModel->where('province','in',$province.',不限');$list = $sqlModel
            ->fetchSql(false)
            ->paginate(['list_rows'=>20,'query' => request()->param()]);
