The SitePoint PHP blog has part three of their "create your own Twitter widget" series posted today. This is the last post of the series and involves a little cleanup on the data pulled from the Twitter API.
In part 1 of this series, we examined the Twitter API, created a PHP TwitterStatus class, and imported the latest tweets in JSON format. In Part 2, we parsed the Twitter data, replaced links, and generated the complete HTML for our widget. In this last post, we'll cache our widget and translate tweet dates into a friendlier format - download the full source code here.
They talk about caching the data pulled back from the API (making it faster and less resource-intensive) and how to parse the dates that you get back from the request using the DateTime functionality included with PHP.
