user can access subject_table if valid user_name lies in user_profile, while both in same database , on valid credential outputs table contents of subjects_table.

this code :

get('/api/users/{user_name}',function(request $request,response $response){ $user_name=$request->getattribute('user_name'); $sql="select * subjects_table user_name='$user_name'  user_profile"; //user_name lies in table //how can join 2 tables  //user_name lies table named user_profile

database structure:

table user_profile consists id, user_name, full_name, email_id, password

database structure :

table subjects_table id, subject_name, web_url, image_url

api

api/user/{user_name}
