Oauth with php and without curl?


is there an example how to use my application with php but without curl ?!
all librarys use curl, but my hosting does not support curl

… found an example without curl, but only for oauth2 (Bearer-Token)
link: http://foren.activevb.de/forum/webentwicklung/thread-265/beitrag-266/Twitter-OAuth-using-PHP-without/

how to get from there to oauth with user-Authentication ?
