php - Fetch multiple separated objects. -

- 

$stmt = $db->prepare("select * friend join user on friend.uid=user.uid friend.friendid= ?");  $stmt->bind_param('s',$userid);  if($stmt->execute()){     $user = $stmt->get_result();     while ($obj = $user->fetch_object()) {          $friends[] = $obj;     }     echo json_encode($friends); }

my above code produced array 

[{"uid":"2","firstname":"gem","lastname":"tang"},{"uid":"3","firstname":"james","lastname":"lebron"}]

but wish 2 object instead.

you have array of objects length 2. using javascript can traverse this.

var o = [{"uid":"2","firstname":"gem","lastname":"tang"},{"uid":"3","firstname":"james","lastname":"lebron"}];  for(var = 0; < o.length; i++) {   var row = o[i];   console.log(row.firstname); }
