Get user's name from Facebook Graph API
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 http://graph.facebook.com/1157251270.
I hope I made it clear.
Thank you
The Graph API returns JSON strings, so you can use:
echo json_decode(file_get_contents('http://graph.facebook.com/1157251270'))->name;
or more verbose:
$pageContent = file_get_contents('http://graph.facebook.com/1157251270');
$parsedJson = json_decode($pageContent);
echo $parsedJson->name; // Romanos Fessas
See json_decode — Decodes a JSON string
如果你使用Facebook的PHP SDK，你也可以这样做来查询他们的图形API：
$fb = new Facebook();
$object = $fb->api('/1157251270');
you get it by:
$link = json_decode(file_get_contents('http://graph.facebook.com/1157251270'));
echo $link->name;
