i fixed using great library j7mbo https://github.com/j7mbo/twitter-api-php/blob/master/readme.md

simplest php example retrieving user_timeline twitter api version 1.1

i used code post twitter.

/** url rest request, see: https://dev.twitter.com/docs/api/1.1/ **/ $url = 'https://api.twitter.com/1.1/statuses/update.json'; $requestmethod = 'post';  $postfields = array(     'status' => 'test' );   /** perform request , echo response **/ $twitter = new twitterapiexchange($settings); echo $twitter->buildoauth($url, $requestmethod)              ->setpostfields($postfields)              ->performrequest();
