javascript - PHP - 将 php 数组转换为 JS 对象时遇到问题

Question

我是 php 新手，在将 php array 转换为 JS object 时遇到一些麻烦。我正在尝试获取给定 YouTube 视频的信息。我能够在客户端接收信息，但只能以 php 数组 的形式接收。我尝试使用 $.parseJSON() 但数据被退格和冗余字符污染。
JS(使用 Angular $http):

$http({
    url: "assets/controllers/youtubeInfo.php",
    method: "POST",
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    data: $.param({ getInfo: videoUrl })
}).success(function(data, status, headers, config) {
    //    console.log(JSON.parse(data));
    console.log(data);
}).error(function(data, status, headers, config) { });

PHP 代码:

function get_youtube($url) {
    $youtube = "http://www.youtube.com/oembed?url=".$url."&format=json";

    $curl = curl_init($youtube);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $return = curl_exec($curl);
    curl_close($curl);
    return json_decode($return, true);
}

$url = $videoKey;

// Display Data 
print_r(get_youtube($url));

这是我的输出:

Array
(
    [title] => StarCraft - OST
    [html] => <iframe width="459" height="344" src="https://www.youtube.com/embed/pNt0iVG2VOA?feature=oembed" frameborder="0" allowfullscreen></iframe>
    [provider_name] => YouTube
    [thumbnail_height] => 360
    [author_url] => https://www.youtube.com/user/JisengSo
    [provider_url] => https://www.youtube.com/
    [type] => video
    [height] => 344
    [thumbnail_url] => https://i.ytimg.com/vi/pNt0iVG2VOA/hqdefault.jpg
    [version] => 1.0
    [author_name] => Jiseng So
    [width] => 459
    [thumbnail_width] => 480
)

要获取 JS 对象，只需不对输出进行json_decode(或再次编码)即可:

function get_youtube($url) {
    $youtube = "http://www.youtube.com/oembed?url=".$url."&format=json";

    $curl = curl_init($youtube);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $return = curl_exec($curl);
    curl_close($curl);
    return $return;    // change here
}

$url = $videoKey;

// Display Data 
echo get_youtube($url);    // change here
