PDO fetchAll array to one dimensional

Question

this may be a simple question but am struggling to understand how to solve it. I have a form which allows the user to select either \"custom\" or \"all\" staff\" to assign t

Answer 1

You need to give fetchAll a fetch style

$staff = $select->fetchAll(PDO::FETCH_NUM);

From this link

Answer 2

Take a look at example 2 in the manual. In your first query you can use:

$staff = $select->fetchAll(PDO::FETCH_COLUMN, 0);

And your second array will have the same form as the first array.

Answer 3

If you print_r($staff[$i]) inside the for you would probably get

    Array
    (
        [staffID] => 1
        [0] => 1
    )

which means you should use $staff[$i]['staffID'] instead.

The other alternative, which should work with your current code, is to use PDOStatement::fetchColumn() instead of fetchAll().
