How to sort the following array? array_multisort doesn't seem to do the job.

Array
(
    [2009] => Array
        (
            [name] => 2009
            [20100923WO2010107543A2] => 20100923WO2010107543A2
        )

    [2006] => Array
        (
            [name] => 2006
            [20080403US20080078500A1] => 20080403US20080078500A1
        )

    [1984] => Array
        (
            [name] => 1984
        )

)

It seems you're trying to sort the array based on the keys. Use ksort().
