Kate's Code Derps

Even if you KNOW you will only get a single value from a single row in a keyed selection statement (SELECT id FROM), you will not get just that column value, you get an array from whence you get your variable.

For example:

if ($result = $mysqli->query($query)) {

            $query_row = mysqli_fetch_assoc($result);

            $userID = $query_row[‘id’];

The mysqli_fetch_assoc returns an array with the column name and the value, and you access the value accordingly. There is no way to just get value! (That’s the derp here, for me.)
