How to get facebook page id via php?

Suppose i have a facebook page link http://facebook.com/page_name and i am not the admin of the page. Is it possible to find out the facebook id, profile pics of the page and fan count?

Thanks!

Solution

FB id and some informations: yes. See Graph API docs.

edit: Some code to get id from my app:

$arg = $_REQUEST['arg'];
if ($arg != ''){

        $arg = str_replace(
                array('http://','www.','facebook.com/','/'),
                '',
                $arg
        );

        $elseID = file_get_contents('https://graph.facebook.com/?ids='.$arg.'&fields=id');
        $elseID = json_decode($elseID,true);
        $elseID = $elseID[$arg]['id'];
}
