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.

On the Developer Tutorials blog today, there's a new post talking about the "three easy steps" to making an RSS feed for your blog:

Adding an RSS feed to your site is quick and painless, and can be done with pure PHP (and some kind of data source). After the jump, 3 simple steps to building an RSS feed in php.

The steps are pretty simple - figure out what content you want to serve, set up the basic RSS XML structure, and loop through your data to push it in to the template and echoed out. Some simple example code is included.

In this new tutorial on the IBM developerWorks website, they show you how - with a little simple HTML and PHP - to integrate functionality from the YouTube API into your site.

The YouTube video sharing site allows Web application developers to access public content through its REST-based developer API. [...] This article introduces the YouTube Data API, demonstrates how you can use it to browse user-generated video content; access video metadata, comments and responses; and perform keyword searches.

They help you get started by outlining the format that the YouTube messages use (Atom feeds) and how to run a query against the API and return back the custom data for things like video categories, popularity and the results of keyword searches.

On the Zend Developer Zone, a new tutorial has been posted that anyone looking to "blend feeds" might want to take a look at. It's a guide to using the Zend_Feed component of the Zend Framework to combine the contents of multiple RSS feeds.

As part of my playing around with the Zend Framework, I've decided to make this merged RSS feed using the Zend_Feed component. Actually at the end I've realized that this merged feed idea is quite useless, but at least this post came out of it :-)

He developed it originally as a way to combine his twitter and blog feeds into one thing to provide the latest updates to readers from both in one simple place. He shows how to take in the two feeds, each in its own feed object and merge them into one array. This array is then pushed back out to the visitor an the RSS format (thanks to Zend_Feed_Rss).

Padraic Brady has put together a very comprehensive post on his blog today about using the Zend_Feed component of the Zend Framework to help with the aggregation of content from other sites (like RSS and Atom feeds).

In this entry I explore Zend_Feed from the perspective of someone aggregating RSS and Atom feeds with a view to building a database of uniquely identified content for later presentation in a "Planet" style application. [...] In fact all we create here is a simple command line script to aggregate content frequently (e.g. just set up cron to run it every hour or so) into a database for later presentation.

He guides you through each step of the way:

• Setting Up Database And Models
• The Aggregator Script Foundation
• Using Zend_Feed to get common data for RSS/Atom entries
• Putting It All Together

There's plenty of code (and SQL to insert) in the post and he explains each point well, helping to make the development process smoother. There's even a summary section to toss in a few extra bits of information just in case you missed them along the way.

Just a quick note to all of you Twitter-ers out there - we've added our own account you can follow if you'd like to get the latest PHPDeveloper.org news straight to your client (or cellphone):

Just head over to the Twitter site and follow phpdeveloper to get the latest updates. It uses the Twitter Feed website to pull our feed in and push it out, so you'll get the latest updates as they come out.
