PHP 中 Facebook ID 值的格式不正确

我使用以下代码来检索用户的好友：

$fql_query_url = 'https://graph.facebook.com/fql?q=SELECT+uid,+name,+pic_square+FROM+user+WHERE+uid+IN+(SELECT+uid2+FROM+friend+WHERE+uid1+=+me())+order+by+name&access_token=' . $_SESSION['token'];
$fql_query_result = file_get_contents($fql_query_url);
$fql_query_obj = json_decode($fql_query_result, true);

它工作得很好，只是对于长度超过 11 个数字的任何 Facebook ID，它们会呈现为 1.xxxxxxxxxxxxxE+14 而不是 1xxxxxxxxxxxxxxx。（例如：100000776800425 变为 1.0000077680042E+14）。除了最后一位数字丢失之外，这不会是一个问题。

令人烦恼的是，如果我在地址栏中插入查询 URL，ID 不会改变。如果我查询“SELECT uid2 FROMfriend WHERE uid1 = me()”，ID 也不会更改。

造成这种情况的原因是什么以及如何解决它？谢谢。

编辑：

我至少设法确定值在 json_decode 期间发生了变化，但除此之外，什么都没有。

添加 ini_set(' precision', 20) 解决了它。

原文

I'm using the following code to retrieve a user's friends:

$fql_query_url = 'https://graph.facebook.com/fql?q=SELECT+uid,+name,+pic_square+FROM+user+WHERE+uid+IN+(SELECT+uid2+FROM+friend+WHERE+uid1+=+me())+order+by+name&access_token=' . $_SESSION['token'];
$fql_query_result = file_get_contents($fql_query_url);
$fql_query_obj = json_decode($fql_query_result, true);

It works just fine except that for any Facebook IDs that are more than 11 numbers long, they get rendered as 1.xxxxxxxxxxxxxE+14 instead of 1xxxxxxxxxxxxxx. (ex: 100000776800425 instead becomes 1.0000077680042E+14). This wouldn't be a problem except that the last digit gets lost.

Annoyingly, if I plug in the query URL in the address bar, the IDs don't get changed. The IDs don't get changed either if I query for "SELECT uid2 FROM friend WHERE uid1 = me()".

What is causing this and how do I get around it? Thanks.

Edit:

I've at least managed to determine that the values get changed during json_decode but other than that, nothing.

Edit 2:

Adding ini_set('precision', 20) solved it.
