Engine Yard has recently posted two podcasts looking at the "Future of PHP" as it relates to two of the popular PHP frameworks out there - CakePHP and Zend Framework 2, as interviewed by Davey Shafik.
The first episode is an interview with some of the core ZF2 contributors about the framework and where they think it's headed. They cover the planned roadmap, targets for next year involving PHP 5.4 and 5.5 as well as how it compares to other frameworks out there today.
In the second episode Davey talks with some of the core contributors (and big fans) of the CakePHP framework. They talk about the current state of the framework, changes in the upcoming version and what it's like working with the PHP-FIG (framework interoperability group).
You can listen to each of these via their in-page players or drop their RSS feed into your reader and get these and the latest episodes of the "Cloud Out Loud" podcast as soon as they're released.
