Zend Framework based on PHP and it is object-oriented stuff.
A couple of years ago, PHP sat at the top of the powerful-but-easy-to-use scripting languages heap — at least as far as popularity was concerned. It was installed on most UNIX and Linux-based Web servers. And if you were a programmer, it was easy to get a hosting account that would let you use it. Ruby had been around for quite some time, but not many people were using it. If you wanted to build a Web site using dynamically generated content, but you weren’t sure that you needed to go so far as to use an application server like J2EE, you would very likely use PHP. It was fast, easy to learn, convenient, and you didn’t have to learn Perl.
These howtos will help you to kick start development with Zend Framework 🙂
