Hi everybody..
Im trying to change twitter user status through my app..
I already have the acces token but when i try to post I keep reciving
"Incorrect signature"

Im using php
 and this is the main code:

$config = array
 (
     "requestTokenURL" => "https://api.twitter.com/1/statuses/
update.json",
      "requestTokenMethod" => "POST",
      "signatureMethod" => "HMAC-SHA1",
     "consumerKey" => "********************",
      "consumerSecret" => "**********************"
    );

$requestParameters2 = array
  (
    "oauth_consumer_key" => $config['consumerKey'],
    "oauth_nonce" => md5(time()),
    "oauth_signature_method" => $config['signatureMethod'],
        "oauth_token" =>  $oauthToken,
        "oauth_timestamp" => time(),
        "oauth_verversion" => "1.0",
        "status" => urlencode("HeyThere")
   );

$signatureParameters2 = array();
foreach ($requestParameters2 as $parameter2 => $value2)
{
    $signatureParameters2[] = rfc3986_encode($parameter2) . '=' .
rfc3986_encode($value2);
}

$signatureParameters2 = rfc3986_encode(implode('&',
$signatureParameters2));


$baseString =
urlencode(rfc3986_encode($config['requestTokenMethod'])
             ."&".rfc3986_encode($config['requestTokenURL'])
             ."&".$signatureParameters2);

$key = rfc3986_encode($config['consumerSecret']) ."&".
rfc3986_encode($tokenSecret);

$signature = base64_encode(hash_hmac('sha1', $baseString, $key,
true));
$RFC3986signature = rfc3986_encode($signature);

///// Im olso using this function to code:
function rfc3986_encode($string)
{
    $result = rawurlencode($string);
    $result = str_replace('%7E', '~', $result);
    $result = str_replace('=', '%3D', $result);
    $result = str_replace('+', '%2B', $result);

    return $result;
}

//////////////this is my header///////

Authorization: OAuth oauth_consumer_key="MIEedQq2dC0ttGgZQ0x***",
oauth_nonce="6c6a3cf5eeee04125e84f563c668b622",
oauth_signature_method="HMAC-SHA1", oauth_timestamp="1301954345",
oauth_token="114032855-6Lc1pnLLx2qhy0YrerDGDlUEucLJAPTgUpytYiPT",
oauth_signature=aw2S42pl%2BXuJKgua06y8kNQ2zoI%3D, oauth_version=1.0,
status="HeyThere"

/////////////// thats it /////////////
I know is much to ask to see all this code but Im so stuck and the
fact to be so close to have it done makes it worst hehe..

Thanks..
