You can debug a graph object using Facebook graph API with PHP-cURL, by doing a POST to

https://graph.facebook.com/v1.0/?id={Object_URL}&scrape=1

to make thing easier, we can wrap our debugger within a function:

function facebookDebugger($url) {

        $ch = curl_init();
              curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v1.0/?id='. urlencode($url). '&scrape=1');
              curl_setopt($ch, CURLOPT_POST, 1);
              curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
              curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        $r = curl_exec($ch);
        return $r;

}

though this will update & clear Facebook cache for the passed URL, it's a bit hard to print out each key & its content and avoid errors in the same time, however I recommended using var_dump() or print_r() OR PHP-ref

usage with PHP-ref

r( facebookDebugger('http://retrogramexplore.tumblr.com/') );
