PHP class or library to allow tweeting from a website

Question

I know there are quite a few libraries out there that that allow Twitter to be integrated into a website. But I haven't yet found what I am looking for (or maybe my understanding of twitter API is lacking). I want to be able to tweet events that occur on my website - BUT in addition, I want to be able to add tweeted from www.example.

For instance, when I send tweets from my blackberry or iphone (or indeed from some other sites), underneath the tweet, there is a message that says, tweeted from (for example blackberry). Does anyone know of a PHP library or class that allows me to send tweets but also with a kind of 'signature' that says where the tweet was sent from?

Edit

Additionally, I want users to be able to tweet from my website. When they tweet, I would like the tweet to say that where it came from (for example, like it does for blackberry phones etc, as I described above).

It is not clear to me whether I still need a PHP application for this requirement, and also how to implement it. Do I need an additional library for allowing users to tweet from my website?

Note: my users do not log into my website using a twitter login, so my website does not have access to a users Twitter username/password etc.

Answer 1

First you must register an app at http://twitter.com/apps, then you can use this twitter class -> http://classes.verkoyen.eu/twitter_oauth

I wrote a tutorial on how to do this http://blog.cmstutorials.org/reviews/general/how-to-update-your-twitter-status-using-php , just follow the steps and you should be good to go

edit: how to include a link

you can write function to get a shortened url because you only have 140 charachters you can then use this function:

function getBitlyUrl($url)
  {
                $bitlylogin = 'your login name';
                $bitlyapikey= 'your api key';
                $bitlyurl = file_get_contents("http://api.bit.ly/shorten?version=2.0.1&longUrl=".$url."&login=".$bitlylogin."&apiKey=".$bitlyapikey);
                $bitlycontent = json_decode($bitlyurl,true);
                $bitlyerror = $bitlycontent["errorCode"];
                if ($bitlyerror == 0) {
                $bitlyurl = $bitlycontent["results"][$url]["shortUrl"];
                }
                else $bitlyurl = "error";
                return $bitlyurl;
  }

then just call it like this:

$url = getBitlyUrl('yourlink');

you can then just add $url to your tweet

Answer 2

You need to create an application in twitter. And tweet via that application (using API) on twitter. the 'via XYZ' will be automatically added.
