PHP Integrating PHP with Databases Using Relational Tables Using a Prepared Statement

Call to undefined method

I keep getting uncaught exception errors with "call to undefined method" when I'm using the methods defined in the code challenges, specifically on the PHP course. Is this actually wrong? It looks exactly the same as the code in the example video to me.

index.php
<?php
function get_member($member) {
    include("connection.php");

    try {
      $results = $db->prepare(
          "SELECT member_id, email, fullname, level
          FROM members WHERE member_id = ?"
      );
     $db->bindParam(1, $member, PDO::PARAM_INT);
      $db->execute();
    } catch (Exception $e) {
      echo "bad query";
    }

    $members = $results->fetchAll();
    return $members;
}

The methods you're using are fine, it's just that you've stored the prepared SQL in a $results variable, so you'll need to call the bindParam and execute methods via $results instead of $db.
