PHP如何转换关联数组？

I have an array which get from POST data

Array
(
    [date_from] => Array
        (
            [0] => 01/10/2015
            ...
        )

    [date_to] => Array
        (
            [0] => 01/11/2015
            ...
        )

    [price_eur] => Array
        (
            [0] => 8
            ...
        )

    [price_usd] => Array
        (
            [0] => 9
            ...
        )

)

And I want to transform it to:

Array
(
    [0] => Array
        (
            ['date_from']   => 01/10/2015
            ['date_to']     => 01/11/2015
            ['price_eur']   => 8
            ['price_usd']   => 9
        )

    ...
)
