Zend_Service_Twitter provides a client for the Twitter REST API. Zend_Service_Twitter allows you to query the public timeline. If you provide a username and password for Twitter, it will allow you to get and update your status, reply to friends, direct message friends, mark tweets as favorite, and much more. Zend_Service_Twitter is implementing a REST service, and all methods return an instance of Zend_Rest_Client_Result. Zend_Service_Twitter is broken up into subsections so you can easily identify which type of call is being requested. account makes sure that your account credentials are valid, checks your API rate limit, and ends the current session for the authenticated user. status retrieves the public and user timelines and shows, updates, destroys, and retrieves replies for the authenticated user. user retrieves friends and followers for the authenticated user and returns extended information about a passed user. directMessage retrieves the authenticated user's received direct messages, deletes direct messages, and sends new direct messages. friendship creates and removes friendships for the authenticated user. favorite lists, creates, and removes favorite tweets. block blocks and unblocks users from following you. With the exception of fetching the public timeline, Zend_Service_Twitter requires authentication to work. Twitter currently uses HTTP Basic Authentication. You can pass in your username or registered email along with your password for Twitter to login. The following code sample is how you create the Twitter service, pass in your username and password, and verify that they are correct. account->verifyCredentials(); ]]> You can also pass in an array that contains the username and password as the first argument. 'foo', 'password' => 'bar'); $twitter = new Zend_Service_Twitter($userInfo); // verify your credentials with Twitter $response = $twitter->account->verifyCredentials(); ]]> verifyCredentials() tests if supplied user credentials are valid with minimal overhead. account->verifyCredentials(); ]]> endSession() signs users out of client-facing applications. account->endSession(); ]]> rateLimitStatus() returns the remaining number of API requests available to the authenticating user before the API limit is reached for the current hour. account->rateLimitStatus(); ]]> publicTimeline() returns the 20 most recent statuses from non-protected users with a custom user icon.
