In this post we will look into accessing Twitter REST API in PHP. This can be useful if you need to post Tweets from your PHP application or anaylze, search Tweets. In the following examples we will use the twitter-api-php PHP wrapper for Twitter v1.1 API. Although there are a few wrappers around, this one I like for its simplicity.
He helps you get the library installed (via Composer) and create an application on the Twitter side at apps.twitter.com. Sample code is included showing how to connect to the API with your credentials, including handling the OAuth authorization piece. From there he shows two examples of action to make on the API: posting a new tweet and searching for new tweets based on a query string.
