快速将多维数组与自定义键组合在一起

Question

基于这些数据：

Array
(
    [from] => Array
        (
            [0] => Array
                (
                    [0] => 2015-08-23 15:33:14
                    [1] => 2015-08-23 15:38:01
                )

            [1] => Array
                (
                    [0] => 2015-08-23 09:39:23
                    [1] => 2015-08-23 15:44:23
                )

        )

    [to] => Array
        (
            [0] => Array
                (
                    [0] => 2015-08-23 15:38:01
                    [1] => 2015-08-23 15:42:22
                )

            [1] => Array
                (
                    [0] => 2015-08-23 15:44:23
                    [1] => 2015-08-23 18:15:38
                )
        )

)

我需要这样的结果：array [from] [0] [0]与array [to] [0] [0]结合作为数组[0] [0]

[0] => Array
    (
        [0] => Array
            (
                [from] => 2015-08-23 15:33:14
                [to] => 2015-08-23 15:38:01
            )
        ...
    )
...

我尝试了很多循环（它太丑了）我怀疑当大量数据时性能不好

我认为这样可以解决问题。

$count1 = count($data);
$result = array();
for($i = 0; $i < $count1; $i++) {
    $count2 = count($data['from'][$i]);
    for($j = 0; $j < $count2; $j++) {
        $result[$i][$j] = array(
            "from" => $data['from'][$i][$j],
            "to" => $data['to'][$i][$j]
        );

    }
}
