7.2 Example of three latest tweets from BREAKINGNEWS. This is the actual request we are sending Twitter. Using ‘echo’ to see what commands are being sent to Twitter is a great debugging tool. We will leave this in for now, but do remember to remove it once you feel comfortable with what these calls look like. Let’s add one more API function. Creating getPublicTime API Function First, let’s see what parameters Twitter supports for this API call. In this case, there is just one: ‘since_id.’ This
callback does not always work. If that happens, try using the following workaround: http://127.0.0.1:8000/twitter_callback. If this does not work, try this. You can use bit.ly, a URL-shortening service. Just shorten the url “http://localhost:3000/twitter_callback” and register the shortened URL as the callback in your Twitter app. For this method, you have to create another Twitter OAuth app for development so that the callback URLs can differ. (Thanks to Toni for this workaround:
are from anyone—a slight but important difference. Now let’s add a few new API calls. Edit parseTwitter.php We have added new tabs to our UI. Now we need to account for the new tabs in our parsing statement. Open parseTwitter.php, and after the following lines: case ‘direct’: { $messages=$twitter->getMessages(‘xml’); return ➥call_direct($messages); } break; Add these lines: case ‘rt_by_me’: { $messages=$twitter->getRTByMe(‘xml’); return ➥call_timeline($messages); } break; case ‘rt_to_me’: {
the destroy method in the beginning of this hour, we could use either POST or DELETE for this method call. We are going to use DELETE because it’s more informative when we read the code. Either way will work; however, using DELETE could prove to be more future proofed as Twitter continues to evolve the API set. Save and close the file. Now let’s give it a shot. Open index.php and click Favorites. Now click ‘Del’ on one of the messages. You should get an XML return similar to Figure 14.3 that
