Twitter 401 not authorized PHP & Abraham Williams Twitter

Question

I've been using Abraham Williams Twitter OAuth Library and it was a breeze setting everything up, except for one thing. I try to post a message to twitter and get a 401 not authorized. I've been searching the Internet for answers, I tried getting new Consumer keys but nothing seems to work.

This is the code I'm using to post a test tweet to Twitter.

// Connection
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, OAUTH_TOKEN, OAUTH_TOKEN_SECRET);

// Posten
$connection->post('statuses/update', array('status' => "Dit is een tweet via de Twitter API"));
// Error afhandeling
$httpc = $connection->http_code;
if($httpc == 200) {
    echo 'Tweet posted!';
} else {
    echo "Fail!";
}

And this is the error I get. I don't have a Callback URL. Should I have one?

I fixed it using another great library from J7mbo https://github.com/J7mbo/twitter-api-php/blob/master/README.md

Simplest PHP example for retrieving user_timeline with Twitter API version 1.1

I used this code to post to Twitter.

/** URL for REST request, see: https://dev.twitter.com/docs/api/1.1/ **/
$url = 'https://api.twitter.com/1.1/statuses/update.json';
$requestMethod = 'POST';

$postfields = array(
    'status' => 'Test'
);


/** Perform the request and echo the response **/
$twitter = new TwitterAPIExchange($settings);
echo $twitter->buildOauth($url, $requestMethod)
             ->setPostfields($postfields)
             ->performRequest();
