php array 2维数组成1维

Question

大家好，我想从数组2维度创建新的1数组维度，代码如下：

[0] => Array(
    [photo_data_id] => 0
    [photo_image] => Array
        (
            [0] => 37a.jpg
        )

    [photo_status] => 1
)

[1] => Array(
    [photo_data_id] => 1
    [photo_image] => Array
        (
            [0] => 6.jpg
            [1] => 6a.jpg
            [2] => 20141001_073231.jpg
        )

    [photo_status] => 1
 )
 [2] => Array(
        [photo_data_id] => 2
        [photo_image] => Array
            (
                [0] => 20.jpg
                [1] => 21.jpg
                [2] => 22.jpg
                [3] => 23.jpg
                [4] => 24.png
            )

        [photo_status] => 1
 )

和我想要的结果如下，而不是存储到数据库中：

[0] => Array(
        [photo_data_id] => 0
        [photo_image] => 37a.jpg
        [photo_status] => 1
)

[1] => Array(
        [photo_data_id] => 1
        [photo_image] => 6.jpg
        [photo_status] => 1
)
[2] => Array(
        [photo_data_id] => 1
        [photo_image] =>  6a.jpg
        [photo_status] => 1
)
[3] => Array(
        [photo_data_id] => 1
        [photo_image] => 20141001_073231.jpg
        [photo_status] => 1
)

[4] => Array(
        [photo_data_id] => 2
        [photo_image] => 20.jpg
        [photo_status] => 1
)

[5] => Array(
        [photo_data_id] => 2
        [photo_image] => 21.jpg
        [photo_status] => 1
)
[6] => Array(
        [photo_data_id] => 2
        [photo_image] =>  22.jpg
        [photo_status] => 1
)
[7] => Array(
        [photo_data_id] => 2
        [photo_image] => 23.jpg
        [photo_status] => 1
)
[8] => Array(
        [photo_data_id] => 2
        [photo_image] => 24.jpg
        [photo_status] => 1
)

请帮助我，我是新手，谢谢之前：）

$result = array();

foreach ($array1 as $item) {
   foreach ($item['photo_image'] as $image) {
       $result[] = array(
           'photo_data_id' => $item['photo_data_id'],
           'photo_image' => $image,
           'photo_status' => $item['photo_status'],       
       );
   }
}

print_r($result);
