无法解析来自 Facebook 图表的响应

Question

我正在尝试确定是否已为用户授予“publish_action”权限（使用 php）。

我可以查询图表了，我只是停留在解析响应以获取 publish_actions = 'granted'。

查询是：

$user_permissions = "https://graph.facebook.com/me/permissions?access_token=" .$access_token;

$permissions = json_decode(file_get_contents($user_permissions));

如果我打印响应

print_r($permissions);

我明白了……

stdClass 对象 ( [data] => 数组 ( [0] => stdClass 对象 ( [权限] => 已安装 [状态] => 授予) [1] => stdClass 对象 ( [permission] => public_profile [status] =>granted ) [2] => stdClass 对象 ( [permission] => publish_actions [status] => grant ) ) )

可捕获的致命错误：stdClass 类的对象无法转换 串起来

基本上我只是希望能够在 php 中分配一个变量 if publish_actions[status] == 'granted'

对此的任何帮助将不胜感激。

更新

尝试以下 Sahil 的建议：

$user_permissions = "https://graph.facebook.com/me/permissions?access_token=" .$access_token;

$permissions = json_decode(file_get_contents($user_permissions, TRUE));

$hasPublishPerm = false;
print_r($permissions['data']);
print_r($permissions);
foreach($permissions['data'] as $permission){
   if($permission['permission']=="publish_actions" && 
      $permission['status']=="granted"){
        $hasPublishPerm = true;
        break;
   }
}

if($hasPublishPerm){
   echo "User has granted the publish permission";
}
else{
   echo "User has NOT granted the publish permission";
}

我收到此错误：

致命错误：不能在...中使用 stdClass 类型的对象作为数组

就这么做-

$hasPublishPerm = false;
foreach($permissions['data'] as $permission){
   if($permission['permission']=="publish_actions" && 
      $permission['status']=="grantedd"){
        $hasPublishPerm = true;
        break;
   }
}

if($hasPublishPerm){
   echo "User has granted the publish permission";
}
else{
   echo "User has NOT granted the publish permission";
}
