php循环遍历带有重复索引的数组

I am trying to loop through an array with duplicate indexes. But it only prints 3 times not all of them. I want to print all values in the array is that possible?

我试图循环使用重复索引的数组。但它只打印3次而不是全部。我想打印数组中的所有值是否可能？

Here is my PHP code:

这是我的PHP代码：

$data['Video'][0]['name']='a';
$data['Video'][1]['name']='b';
$data['Video'][1]['name']='c';
$data['Video'][3]['name']='d';
$data['Video'][3]['name']='e';

foreach ($data['Video'] as $video) {
    print_r($video);
}

And here is the output of that code:

以下是该代码的输出：

Array
(
    [name] => a
)
Array
(
    [name] => c
)
Array
(
    [name] => e
)

#1

Please avoid duplicate entry of keys otherwise try this,

请避免重复输入密钥，否则请尝试此操作，

  $data['Video'][]['name']='a';
  $data['Video'][]['name']='b';
  $data['Video'][]['name']='c';
  $data['Video'][]['name']='d';
  $data['Video'][]['name']='e';

  foreach ($data['Video'] as $video) {
      print_r($video);
  }

Well, the duplicate indexes negate each other. So this is expected behavior. So when you set this in your code:

好吧，重复的索引相互否定。所以这是预期的行为。所以当你在代码中设置它时：

$data['Video'][0]['name']='a';
$data['Video'][1]['name']='b';
$data['Video'][1]['name']='c';
$data['Video'][3]['name']='d';
$data['Video'][3]['name']='e';

It really just means this:

它真的只是意味着：

$data['Video'][0]['name']='a';
$data['Video'][1]['name']='c';
$data['Video'][3]['name']='e';

The newer data assigned to the keys 1 and 3 overwrite what was previously there.

分配给键1和3的较新数据会覆盖之前的数据。
