I'm using the facebook php library to authenticate users to my app, it's working fine but for some reason facebook is appending the characters
$fbLoginUrl = $fb->getLoginUrl(array(
'scope' => 'email,publish_stream,user_birthday,user_photos,friends_photos',
'redirect_uri' => 'http://myapp.net/auth'
On Facebook developer blog, it was told that, if you explicitly set the
redirect_uri param, you won't get the
#_=_ appended to the callback uri. But this is not the case. You still get those characters even on setting
redirect_url field. But that won't have any effect on your flow.
