How to display data from database in array PHP 7

my database looks like this:

id | name | items
1  | abc  | "first item", "second item", "third item"
2  | def  | "a item", "b item", "c item"
3  | ghi  | "x item", "y item", "z item"

I need every value of array in different div. My values for that array are in the same cell in my database. code down here is not working it puts "items" in one div Thanks for your help.

$id = 2; /*for example*/

$sql = "SELECT * FROM myDB WHERE id = '".$id."'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo $row['name'];

    $itemsused=array($row['items']);

    foreach($itemsused as $itemsusedoutput)
    {
      echo "<div>$itemsusedoutput</div>";
    }
  }
}
