twitter oauth authentication and posting tweet not working - php

Question

So I'm trying to post tweets of a user through my application. Whenever I freshly get the oauth_token and oauth_secret, I can post a tweet no problem, However, if I try to save them for later and then post a tweet, I get the error:
object(stdClass)#5 (2) {
["error"]=>
string(27) "Could not authenticate you."
["request"]=>
string(23) "/1/statuses/update.json"
}
Here is the script I use to get the tokens initially:
<?php
require("config.php");
require("twitterOAuth.php");
session_start();
if(!empty($_GET['oauth_verifier']) && !empty($_SESSION['oauth_token']) && !empty($_SESSION['oauth_token_secret'])){
// We've got everything we need
} else {
// Something's missing, go back to square 1
//header('Location: new_index.php');
}
// TwitterOAuth instance, with two new parameters we got in twitter_login.php
$twitteroauth = new TwitterOAuth($consumer_key, $consumer_secret, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret']);
// Let's request the access token
$oauth_token = $_SESSION['oauth_token'];
$oauth_secret = $_SESSION['oauth_token_secret'];
$access_token = $twitteroauth->getAccessToken($_GET['oauth_verifier']);
//post tweet
$result = $twitteroauth->post('statuses/update', array('status' => 'asd '));
// Save it in a session var
$_SESSION['access_token'] = $access_token;
// Let's get the user's info
$user_info = $twitteroauth->get('account/verify_credentials');
?>
And here is the script where I just try to tweet it using the tokens:
<?php
require("config.php");
require_once('twitterOAuth.php');
$oAuthToken = $argv[1];
$oAuthSecret = $argv[2];
$message = $argv[3];
$post_id = $argv[4];
// create a new instance
$tweet = new TwitterOAuth($consumerKey, $consumerSecret, "$oAuthToken", "$oAuthSecret");
//send a tweet
$result = $tweet->post('statuses/update', $message);//array('status' => "$message"));
$tweet_id = $result['id_str'];
?>
Any ideas? I could really use some help here. It worked fine last night and now all the sudden it's not working at all :/
Could the tokens expire and not work after they're not session variables?

Answer 1

/*Try this one it will work proper*/
session_start();
require("config.php");
require_once("twitterOAuth.php");
$access_token = $_SESSION['access_token'];//which you got from callback
/* Create a TwitterOauth object with consumer/user tokens. */
$tweet = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token['oauth_token'], $access_token['oauth_token_secret']);
$tweet->post('direct_messages/new', array('text' => $messageBody, 'screen_name' => $screenName))

Answer 2

Try to use this code (in the second part of your code):
<?php
session_start();
require("config.php");
require_once("twitterOAuth.php");
$oAuthToken = $_SESSION['oauth_token'];
$oAuthSecret = $_SESSION['oauth_token_secret'];
and so on. Does this code work for you?
