php - 如何使用 Facebook PHP SDK v4 访问 GraphObject 中的用户语言

Question

我查询了 Facebook 用户资料并得到以下Facebook\GraphObject语言响应

Facebook\GraphObject Object
(
    [backingData:protected] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 106059522759137
                    [name] => English
                )

            [1] => stdClass Object
                (
                    [id] => 105673612800327
                    [name] => German
                )

            [2] => stdClass Object
                (
                    [id] => 106049856092338
                    [name] => Urdu
                )

        )

)

我正在尝试通过以下代码访问该属性，但无法获取语言数组：

$languages = $Usergraph->getProperty("languages");
$languages_array = array();

print_r($languages);

foreach ($languages as $language){
    $languages_array[] = $language->getProperty('name');
}

print_r($languages_array);

有没有其他方法可以获取语言信息

Answer 1

好的，我在找到我也可以投射我的 GraphObject 的信息后解决了这个问题。所以解决方案将是这样的：

$languages = $Usergraph->getProperty("languages")->asArray();
$languages_array = array();
foreach ($languages as $language){
    $languages_array[] = $language->name;
}

print_r($languages_array);

信息将显示：

Array
(
    [0] => English
    [1] => German
    [2] => Urdu
)
