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

我查询了Facebook用户配置文件，得到了以下关于语言的响应

Facebook\GraphObject

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
                )

        )

)

我试图通过以下代码访问属性，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);

---

是否有其他方法可以获取语言信息

好的，在找到可以转换GraphObject的信息后，我解决了这个问题。因此，解决方案如下：

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

print_r($languages_array);

将显示以下信息：

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