On his blog today, Stefan Mischook has posted his take on some of the killer PHP projects that are out there:

Part of PHP's power is actually found in the variety of open source (free to use) PHP based applications. I'm talking about things like blogs, web frameworks, forums, CMS' etc. I was just thinking, that a list of 'killer' PHP open source projects would be useful

There four on his list so far - WordPress, the Zend Framework, Drupal and Punbb.

To be totally honest about it, we've seen much of the good stuff coming out of the PHP world, in the last few years. PHP developers are leap-frogging ahead with regards to their level of skill and the quality of code they produce.

In this new post, Jackson Miller mentions something that he thinks just might become a Ruby on Rails killer, Tapestry. Fortunately, there's already been a framework implemented with its ideas in mind - the PRADO Framework.

Howard Ship is the guy behind Tapestry which is one of the better component frameworks out there. In a post today he is drawing attention to PRADO which is a PHP component framework that is based on the ideas in Tapestry. I haven't checked out PRADO in a long time but it looks like they are still moving forward and making good progress.

Jackson also mentions the one thing that he really took from Howard's post, that he's "raising the bar" with a challenge that Tapestry will always be the leader in this realm, though.
