You have a few changes to make:

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

try {
  $results = $db->query(
      "SELECT member_id, email, fullname, level
      FROM members
      WHERE member_id = " . $member_id
  );
} catch (Exception $e) {
  echo "bad query";
}

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

}

Could you try this?

<?php function get_member($member_id) { include("connection.php"); try { $result = $db->prepare('SELECT member_id, email, fullname, level FROM members WHERE members.member_id=:member_id'); $result ->bindParam(':memberid', $member_id); $result->execute(); } catch (Exception $e) { echo "bad query"; } return $result; }

I did everything in the first step, and it never would accept my WHERE clause on the 2nd step. I refreshed and just added the argument in the first step and the WHERE clause in the 2nd and it worked.

may be a bug
