如何使用PHP从数据库中获取数据并以适当的方式表示

Question

I have a database structure :

WORK | NAME | USER_ID
  5  | UL7  |  7
  5  | LL5  |  7
  6  | UR9  |  7
  6  | UL7  |  7

i have wrote a function to fetch the data from db which is :

function fetchRegion($user_id){
  global $mysqli;
  $stmt = $mysqli->prepare("SELECT name,work from region WHERE user_id =?");
  $stmt->bind_param("s",$id);
  $stmt->execute();
  $stmt->bind_result($work,$name);
  while($stmt->fetch()){
  $row[] = array('work'=>$work,'name'=>$name);
  }
  $stmt->close();
  return $row;
  }

Now the problem what i am facing is i want to represent the data as it should display

5 => UL7,LL5 and 6 =>UR9,UL7

But i am getting an output in an array. Now what can be done to represent the data to display in the above format rather in an array.

Thanks in advance!!

You could use the GROUP_CONCAT() function along with GROUP BY in your sql query like this:

SELECT `work`, GROUP_CONCAT(`name`) FROM `region` WHERE `user_id` =? GROUP BY  `name`

Then, the fetched results would be like this:

work | name
------------
5 | UL7,LL5 
6 | UR9,UL7

Hope it helps!
