object to array as in db

[eluser]Pana_Ruplahlava[/eluser]
Ok, here is the situation. I can do it in php easily and i repeat it often, so there must be an easy way to do it in CI, but i dont know how. I started using it yesterday.

So: in db i have field id and field label and i need it put it into select. as id as value and label as text.

in past 2 hours in user guide i was not able to figure it out.
i assume i have to put it in array so form_dropdown can use it. but how. there must be an easy way... anybody can help?

this is what i was able to get from DB

Code:

Array
(
    [0] => Array
        (
            [label] => Fotogalerie
            [id] => 2
        )

    [1] => Array
        (
            [label] => asdasdasd
            [id] => 4
        )

    [2] => Array
        (
            [label] => asdg
            [id] => 5
        )

)

and i need it looking like

Code:

Array
(
'2'=>'Fotogalerie',
'4'=>'asdasdasd',

...
)

Thx for any help
