Facebook SDK和PHP数组

我正在使用Facebook SDK和PHP。一切正常，但有一部分我遇到了麻烦，那就是将特定字段值存储到变量中

这是获取并打印信息的代码

if ($session){ //if we have the FB session

    $user_profile = (new FacebookRequest($session, 'GET', '/me/accounts?fields=id,name,access_token'))->execute()->getGraphObject(GraphUser::className());
    //do stuff below, save user info to database etc.
    echo "Session Set.";

    echo '<pre>';
    print_r($user_profile); //Or just print all user details
    $variable = print_r($user_profile, TRUE);
    echo '</pre>';

    // How do I get the first 'id', 'name', and 'access_token'
    // How do I get the second 'id', 'name', and 'access_token'
}

如何获取[id]、[name]和[access_token]并将它们存储在变量中，以便最终将它们保存到db中？

因此，如果您试图使用PHP与Facebook SDK集成，我强烈建议您阅读Facebook的开发者指南：

以下是关于使用Facebook SDK的非常有用的YouTube教程：

以下是他关于Facebook SDK的GitHub文件：

让我想到如何获取Facebook页面ID和访问令牌的文件是add-Page-tab.php

以下是将为您提供信息的代码片段：

$pages=$fb->get（'/me/accounts'）；
$pages=$pages->getGraphEdge（）->asArray（）；
?>
Session Set.

    [backingData:protected] => Array
        (
            [data] => Array
                (

                        (
                            [id] => XXXXXXXX

if(isset($_POST['submit'])) {

    $page = $page->getGraphNode()->asArray();

    echo "Access Token: " .$page['access_token'] . "<br/><br/>";

    echo "Page Id: " . $page['id'];

    // print_r($page);
