PHP Twitter API (Abraham's) - Could not authenticate issue

I am having some problems with implementing the twitter api. I am using Abraham's method to connect to Twitter but I get this error:

object(stdClass)#25 (2) {
["error"]=>
string(27) "Could not authenticate you."
["request"]=>
string(302) "/1/account/verify_credentials.json?oauth_consumer_key=79CrBl2oYlaATF7YOn0New&oauth_nonce=014df8945398b9605b78703829f93c45&oauth_signature=7OnRBeraaGxXgLbTNQ3%2BFdMAIPs%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1314776180&oauth_token=U7iPIyqv7IJyq1VkvKsf06KE6KQOtVDPBEwwqRjhg&oauth_version=1.0"
}


This is my code:

$to = new TwitterOAuth();
$tok = $to->getRequestToken(CURRURL);
$request_link = $to->getAuthorizeURL($tok);
$_SESSION['oauth_access_token']= $tok['oauth_token'];
$_SESSION['oauth_access_token_secret'] = $tok['oauth_token_secret'];

if ((!isset($_SESSION['oauth_access_token'])) || ($_SESSION['oauth_access_token'])=='') {

$to = new TwitterOAuth($_SESSION['oauth_access_token'], $_SESSION['oauth_request_token_secret']);
$token_credentials = $to->getAccessToken($_REQUEST['oauth_verifier']);
$_SESSION['oauth_access_token'] =$token_credentials['oauth_token'];
$_SESSION['oauth_access_token_secret'] = $token_credentials['oauth_token_secret'];
} else {
$connection = new TwitterOAuth($access_token['oauth_token'], $access_token['oauth_token_secret']);
$user_info = $to->get('account/verify_credentials');

//die(var_dump($user_info));

$data = array(
"twitter" => array(
"oauth_provider" => "twitter",
"oauth_uid" => $user_info->id,
"first_name" => $user_info->name,
"last_name" => "",
"username" => $user_info->screen_name,
"email" => "",
"gender" => "",
"hometown" => "",
"location" => $user_info->location
)
);

array_push($social,$data);

}


I have been banging my head to the wall over this, so any suggestions would greatly be appreciated!

First, when you initialize your method TwitteroAuth you've to pass also your consumer_key and consumer_secret that Twitter gives you.

Second, after the getAuthorizeURL you've to redirect the user to the Twitter website to allow them to accept you access to their information.

After the user allows Twitter to use its own information, Twitter redirects the user to your callback page. In your example is what contains the constant CURRURL.

You'll receive two new information with your URL the oauth_token and oauth_token_secret and you gonna initialize TwitterOAuth again with this, the consumer_key, consumer_secret, and theses two new parameters. TwitterOAuth(key, secret, token, token_secret)

And only after it you'll be able to get the user information with $user_info = $to->get('account/verify_credentials');
