我在下面的 PHP 代码中有一个数组，我想将该数组转换为按数据值分组。简化数组总是很困难
Array
(
[0] => Array
(
[video_id] => 14
[video_title] => test1
[video_category_name] => Beginner
[video_category] => 1
)
[1] => Array
(
[video_id] => 18
[video_title] => test
[video_category] => 1
[video_category_name] => Beginner
)
[2] => Array
(
[video_id] => 17
[video_title] => first
[video_category] => 3
[video_category_name] => Mobility
)
[3] => Array
(
[video_id] => 19
[video_title] => second
[video_category] => 3
[video_category_name] => Mobility
)
)
我期望这个数组：
(
[0] => Array
(
[ctg_name] => Beginner
[cat_id] => 1
[ data] => Array
(
(
[0] => Array
(
[video_id] => 14
[video_title] => test1
[video_category_name] => Beginner
[video_category] => 1
)
[1] => Array
(
[video_id] => 18
[video_title] => test
[video_category] => 1
[video_category_name] => Beginner
)
)
)
[1] => Array
(
[ctg_name] => Mobility
[cat_id] => 3
[ data] => Array
(
[0] => Array
(
[video_id] => 17
[video_title] => first
[video_category] => 3
[video_category_name] => Mobility
)
[1] => Array
(
[video_id] => 19
[video_title] => second
[video_category] => 3
[video_category_name] => Mobility
)
)
)
)
我尝试过这个，但没有得到我预期的结果。
foreach($video as $val){
$result[$val['video_category']][] = $val;
}
它返回如下：
Array
(
[1] => Array
(
[0] => Array
(
[video_id] => 14
[video_title] => test1
[video_category_name] => Beginner
[video_category] => 1
)
[1] => Array
(
[video_id] => 18
[video_title] => test
[video_category] => 1
[video_category_name] => Beginner
)
)
[3] => Array
(
[0] => Array
(
[video_id] => 17
[video_title] => first
[video_category] => 3
[video_category_name] => Mobility
)
[1] => Array
(
[video_id] => 19
[video_title] => second
[video_category] => 3
[video_category_name] => Mobility
)
)
)
有谁有有效的方法来做到这一点？
请帮我
谢谢
