Does the while loop pull two separate strings from the row and fullname fields or an array?
As shown in the video, I was confused about what kind of data type the while loop pulls from the database. The video suggest the data is pullied as '$row: 'actor', 'John Livingston' Is this supposed to represent one $row variable with an array as a value? I'm not sure) so I reviewed some of the questions under the video to see if anyone else had the same problem understanding this.
The highlighted best answer from Zach Billingsley to a question headed as 'Confused. How does this code work?' dated 2017 suggests that the while loop pulls the data as two strings like this $row['role'] = 'actor' and then $row['fullname'] = 'Ron Livingston' and not as a single array?
Was this answer correct or is the r$row = $result->fetch(PDO::FETCH_ASSOC actually pulling just a single array and (for example) assigning as $row = ('actor','Ron Livingston', ) ?

Hi there, Matt Nickolls! The
$row is an associative array. It contains a "role" key and a "fullName" key. So the
$row for say Keanu Reeves would look like:
$row = array("role" => "star", "fullName" = "Keanu Reeves";
Then we take the role and create yet another associative array for
$item now might have something like:
array("title" => "Speed", "producer" => ["Jan De Bont"], "star" => ["Keanu Reeves", "Sandra Bullock"]);
The value at the "role" key is in itself an array and you are appending to it each time you hit a new person with the same role.
Hope this helps!
