order by timestamp without a database?
<p>I have to store some info (timestamp of post, title and link) from various feeds (facebook,twitter,rss and some custom xml) without using a database. So I'm writing what I need to xml files and then pulling everything in using simplexml. This works fine. However, I need output the info from the various feeds in to a un-ordered list that's ordered by the timestamp. I don't know how to do this. I can get the info from each feed aggregated in to one array but how do I order by the timestamp before I output it in to html?</p>
