如何使用Facebook PHP SDK v4訪問GraphObject內部的用戶語言

Question

我查詢了Facebook用戶個人資料，並獲得以下響應Facebook\\GraphObject for Languages

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
                )

        )

)

我正在嘗試通過以下代碼訪問屬性，但無法獲取語言數組：

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

print_r($languages);

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

print_r($languages_array);

還有其他方法可以獲取語言信息嗎

Answer 1

好吧，在找到可以投射GraphObject的信息后，我解決了該問題。 所以解決方案將是這樣的：

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

print_r($languages_array);

信息將顯示：

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