hi..

can you explain why
'request_token='.$tokens['request_token'] is there twice in..

echo 'login_url=http://api.local/oauth_login?' .
'request_token='.$tokens['request_token'].
'&request_token='.$tokens['request_token'].
'&request_token_secret='.$tokens['request_token_secret'].
'&oauth_callback_confirmed=true'

??
