检查数组中的user_id

I have logged as approver_id ='897'. Request table have request_id,approver_id

request_id  approver_id
 005         897
 006         [897,91] 
 007         91

I want to fetch the records where $approver_id is 897In a laravel query I have to get the row where the approver_id is 897 so expected 005 and 006

 $user=".."; //Query stuff
 $user=$user->where('request.flag','=','1')
 ->orwhereIN('asset_request.approver_id',array($approver_id))->get();

I didn't get any rows how to check the approver_idis in the table row

i don't recommend to store information like this but if you need then store it as a json. And then you can fetch it like this

$requests = Request::whereJsonContains('approver_id',[$approver_id])->get();

Here Request is a model class for requests table
