<?php
/**

include_once("config.php");
/*
unset($_SESSION['trequest_token_secret']);
unset($_SESSION['taccess_oauth_token']);
unset($_SESSION['taccess_oauth_token_secret']);
*/
$oauthc = new OAuth($oauth['twitter']['consumerkey'],
$oauth['twitter']['consumersecret'],
OAUTH_SIG_METHOD_HMACSHA1,OAUTH_AUTH_TYPE_URI); //initiate
if(empty($_SESSION['trequest_token_secret'])) {
//get the request token and store it
$request_token_info = $oauthc->getRequestToken($oauth['twitter']['requesttokenurl']); //get request token
$_SESSION['trequest_token_secret'] = $request_token_info['oauth_token_secret'];
header("Location: {$oauth['twitter']['authurl']}?oauth_token=".$request_token_info['oauth_token']);//forward user to authorize url
}
else if(empty($_SESSION['taccess_oauth_token'])) {
//get the access token - dont forget to save it
$request_token_secret = $_SESSION['trequest_token_secret'];
$oauthc->setToken($_REQUEST['oauth_token'],$request_token_secret);//user allowed the app, so u
$access_token_info = $oauthc->getAccessToken($oauth['twitter']['accesstokenurl']);
$_SESSION['taccess_oauth_token']= $access_token_info['oauth_token'];
$_SESSION['taccess_oauth_token_secret']= $access_token_info['oauth_token_secret'];
}
if(isset($_SESSION['taccess_oauth_token'])) {
//now fetch current users profile
$access_token = $_SESSION['taccess_oauth_token'];
$access_token_secret =$_SESSION['taccess_oauth_token_secret'];
$oauthc->setToken($access_token,$access_token_secret);
$data = $oauthc->fetch('http://twitter.com/account/verify_credentials.json');
$response_info = $oauthc->getLastResponse();
echo "<pre>";
