请求应该失败，因为访问你需要获得一个访问令牌的网址。所以，Facebook的返回

The request should fail, because to access that URL you need to obtain an access token. So Facebook returns

{
   "error": {
      "message": "An access token is required to request this resource.",
      "type": "OAuthException",
      "code": 104
   }
}

沿着有400错误的请求的地位。此外，因为你打开一个URL的file_get_contents的第二个参数应该是假的（没有一点搜索包含路径，如果你知道它不存在）。

with along with a "400 Bad Request" status. Additionally since you're opening an URL the second parameter of file_get_contents should be false (there is no point to search the include path, if you know it's not there).

要仍然得到来自Facebook的响应，而忽略你能做的错误：

To still get the response from Facebook and ignore the error you can do:

$url = 'http://graph.facebook.com/10150624051911279/photos/all';
$context = stream_context_create(array(
  'http' => array(
     'ignore_errors'=>true,
     'method'=>'GET'
     // for more options check http://www.php.net/manual/en/context.http.php
   )
));
$response = json_decode(file_get_contents($url, false, $context));
