<?php

/**
 * Very basic streaming API example. In production you would store the
 * received tweets in a queue or database for later processing.
 *
 * Additional comments by artumi-richard
 *
 * Instructions:
 * 1) If you don't have one already, create a Twitter application on
 *      https://dev.twitter.com/apps
 * 2) From the application details page copy the consumer key and consumer
 *      secret into the place in this code marked with (YOUR_CONSUMER_KEY
 *      and YOUR_CONSUMER_SECRET)
 * 3) From the application details page copy the access token and access token
 *      secret into the place in this code marked with (A_USER_TOKEN
 *      and A_USER_SECRET)
 * 4) In a terminal or server type:
 *      php /path/to/here/streaming.php
 * 5) To stop the Streaming API either press CTRL-C or, in the folder the
 *      script is running from type:
 *      touch STOP
