Twitter oAuth: getting an error 215 - php

Question

I have the following code in one of my classes:
public function build_httpheader ($options = NULL)
{
if (!$this->oauth_token && !$this->oauth_token_secret && !$this->http_method) {
throw new Exception('The oauth_token, oauth_token_secret and the http method must be set');
}
$url = $this->base_uri;
$url_curl = $this->base_uri;
if ($options) {
$this->options = $options;
$url .= '?';
$url_curl .= '?';
$count = count($options);
foreach($options as $key => $value) {
$count = $count--;
if ($count) {
$url .= '&'.$key.'='.$value;
$url_curl .= '&'.$key.'='.rawurlencode($value);
} else {
$url .= $key.'='.$value;
$url_curl .= $key.'='.rawurlencode($value);
}
}
}
$this->url = $url_curl;
/**
* #internal Create a 32 chars unique string to
* use as the nonce value
*/
list($usec, $sec) = explode(" ", microtime());
$usec = str_replace('0.', '', $usec);
$nonce_str = utf8_encode($sec.$usec.'ABCD'.$sec);
$oauth_nonce = md5($nonce_str);
/**
* #internal Create the initial oAuth array
*/
$oauth = array (
'oauth_consumer_key' => $this->consumer_key,
'oauth_nonce' => $this->$oauth_nonce,
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_token' => $this->oauth_token,
'oauth_timestamp' => time(),
'oauth_version' => '1.0'
);
/**
* #internal generate basic info
*/
$t_oauth = array();
ksort($oauth);
foreach($oauth as $key=>$value){
$t_oauth[] = "$key=" . rawurlencode($value);
}
$base_info = $this->http_method."&" . rawurlencode($url) . '&' . rawurlencode(implode('&', $t_oauth));
$composite_key = rawurlencode($this->consumer_secret) . '&' . rawurlencode($this->oauth_token_secret);
$oauth['oauth_signature'] = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth_string = 'Authorization: OAuth ';
$values = array();
foreach($oauth as $key=>$value) {
$values[] = "$key=\"" . rawurlencode($value) . "\"";
}
$oauth_string .= implode(', ', $values);
$this->http_headers = array ($oauth_string, 'Expect:');
}
public function tw_curl_api_call ()
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->http_headers);
if ($this->http_method == 'POST') {
curl_setopt($ch, CURLOPT_POST, true);
}
if ( ($this->http_method != 'POST') && ($this->http_method != 'GET') ) {
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $this->http_method);
}
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $this->url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
$result = json_decode(curl_exec($ch), TRUE);
$info = curl_getinfo($ch);
curl_close($ch);
return array ('result' => $result, 'info' => $info);
}
Another script uses this class as follows:
$options = array ('resources' => 'help,users,search,statuses');
$tw_wrapper->build_httpheader ($options);
$results = $tw_wrapper->tw_curl_api_call ();
I am however getting an error 215 (bad authentication data). Any ideas (I am aware that there are existing PHP oAuth classes and twitter wrappers, but it does not seem as if any of them has completely migrated to the 1.1 API).

Have you had a look at Codebird? It has support for 1.1 and works well for what I've needed. YMWV of course.
A simple example:
Codebird::setConsumerKey('KEY', 'SECRET');
$cb = Codebird::getInstance();
$cb->setToken('AUTH_KEY', 'AUTH_SECRET');
$result = $cb->statuses_userTimeline(array(
'include_rts' => true,
'screen_name' => 'hansnilsson',
));
