The Graph API returns JSON strings, so you can use:

<pre><code>echo json_decode(file_get_contents('http://graph.facebook.com/1157251270'))-&gt;name;
</code></pre>

or more verbose:

<pre><code>$pageContent = file_get_contents('http://graph.facebook.com/1157251270');
$parsedJson = json_decode($pageContent);
echo $parsedJson-&gt;name; // Romanos Fessas
</code></pre>

See <a href="http://de3.php.net/manual/en/function.json-decode.php"><code>json_decode</code> — Decodes a JSON string</a>

blocks|key|1981153|text|如果你使用的是Facebook的PHP+SDK，你也可以这样做来查询他们的图形API：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1981154|$fb+=+new+Facebook();

I would like to know how is it possible to retrieve a string from an external page.

For example: In a PHP website, the user sends a facebook id, ex: 1157251270

And the website returns the name from <a href="http://graph.facebook.com/1157251270" rel="noreferrer">http://graph.facebook.com/1157251270</a>.

I hope I made it clear.

Thank you

我想知道如何从外部页面检索字符串。例如:在PHP网站中，用户发送一个facebook id，例如: 1157251270网站返回来自的名称。我希望我说得很清楚了。谢谢
