PHP如何转换关联数组？

Question

我有一个从POST数据中获取的数组

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
            ...
        )

)

我想将其转换为：

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

    ...
)

如何转换这个php关联数组？

刚刚解决了这个问题。让我知道它是怎么回事

foreach ($original as $key => $arr){
    foreach ($arr as $x => $y){
        $new[$x][$key] = $y
    }
}
