On the SitePoint PHP blog today there's a new tutorial showing how to use the SimplePie aggregation library to create a "lifestream" website of all of your accounts across the web.

In this tutorial we’ll build a page that gathers up the RSS feeds of all those little bits of your life and presents them all together in one spot. To do that, we’ll use SimplePie, a feed parsing class written in PHP. It’s powerful, it’s open source, and it’s easy to use. We’ll then hack on the output a little, and make it all look gorgeous with HTML and CSS. The techniques we’ll cover are also useful if you find that you need to aggregate RSS from many sources, like a news page.

In their example they pull together accounts from Twitter, Flickr and Last.fm. You can check out the code for their example script here.

John Highland has a quick tutorial showing how to create a lifestream with PHP out of all of the RSS feeds surrounding the multiple social networking and blogging sites you have out there (with the help of SimplePie).

Its not secret, I love social networking, I cant get enough of it. I also love programming and anything internet related. I'm not sure how I came across it, but a PHP based, Object Oriented RSS caching tool named SimplePie caught my attention.

SimplePie offers one piece of functionality that he found particularly useful - the ability to merge RSS feeds easily. He took advantage of the ability and pulled together his Twitter, Flickr, Pownce, Digg and Youtube RSS feeds to make one mega-feed. You can see an example of it in action over on his personal site.
