困在这个问题上,

$lnk = $_REQUEST['link'];
$facebook->setFileUploadSupport(true);
$attachement = array(‘access_token’ => $session['access_token'],
‘source’ =>’@’ . realpath($lnk),
 ‘name’ => ‘my ------ friend’,
‘message’ => ‘m pic;get yours at http://apps.facebook.com//‘
);
$fb_photo = $facebook->api(‘me/photos’,'POST’,$attachement);
