在多维数组中插入键

Question

我创建了一个空数组($results)，其中存储了从foreach循环返回的数据。我对在数组中设置的每个search_tags关键字都这样做。这一切都工作，除了我想添加标签($tag)，它已用于从Instagram api获取数据到多维数组。

$search_tags = array(
    "tag1",
    "tag2",
    "tag3"
);
// create empty array
$results=array();
// Get all the data for the tags we are searching for and put it into an array
foreach ($search_tags as $tag) {
    $medias = $instagram->getTagMedia($tag);
    foreach ($medias->data as $media_obj) {
      array_push($results, $media_obj);
      array_push($results, $tag)
    }
}

我试过用array_push这样做，但这会在数组之后添加标签，而不是在数组内部，如你所见。

Array
(
    [0] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
        )
    [1] => tag1
    [2] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
        )
    [3] => tag2
    [4] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
        )
    [5] => tag3
)

是否有一种方法可以像这样将标签插入到多维数组中:

Array
(
    [0] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
            [tag] => tag1
        )
    [2] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
            [tag] => tag2
        )
    [4] => stdClass Object
        (
            [attribution] => 
            [location] => 
            [filter] => 
            [created_time] => 
            [link] => 
            [type] => 
            [id] => 
            [user] => 
            [tag] => tag3
        )
)

试试这个:

// Get all the data for the tags we are searching for and put it into an array
foreach ($search_tags as $tag) {
    $medias = $instagram->getTagMedia($tag);
    foreach ($medias->data as $media_obj) {
      $media_obj->tag = $tag;
      array_push($results, $media_obj);
    }
}
