Fulworx is a REST framework that uses simple annotations of XWork "Action" implementations to expose restful interfaces. Similar to Struts, Fulworx sits as a controller on top of Restlet. Each action is attached as a resource using Restlets. Standard resources are represented by default as XML (or JSON) using JAXB, but any representation may be specified. Actions may be used in other frameworks such as Struts and Webwork, since they're just XWork implementations.
IrisMVC is an OOP PHP framework that developers can use as a strong and secure foundation on which to build various Web applications following the Model-View-Controller (MVC) pattern. It only provides the basic functionality developers need, without reinventing the wheel, so the learning curve is dramatically short and they should be able to start using it at full capacity in days. The goal is to allow developers to create Web sites faster without needing to learn a whole new PHP framework.
Mojolicious is "Duct Tape For The HTML5 Web". It is powerful with no dependencies out of the box with RESTful routes, plugins, Perl-ish templates, session management, signed cookies, a testing framework, a static file server, I18N, first class Unicode support, and much more. It has a very clean, portable, and object oriented pure Perl API without any hidden magic and no requirements besides Perl 5.10.1. It has a full stack HTTP 1.1 and WebSocket client/server implementation with TLS, Bonjour, IDNA, Comet (long polling), chunking, and multipart support. It has a built-in async I/O Web server supporting EV pluggable event queue, Unix domain sockets, and hot deployment, perfect for embedding. Automatic CGI, FastCGI, and PSGI detection for any deployment situation. It has a JSON and XML/HTML5 parser with an advanced CSS3 selector support. The code is based upon years of experience developing Catalyst.
Ding is a PHP framework that provides dependency injection (by Setter, Constructor, and Method), Aspect Oriented Programming, XML, YAML, Events support, and some JSR 250/330 annotations as bean definition providers, lightweight, can be deployed as a PHAR file, simple, and quick MVC, syslog, TCP client and server with non-blocking sockets, timers, and custom error, signal, and exception handling, PAGI integration (for the Asterisk gateway interface), and PAMI integration (for Asterisk management). It is similar to Java's Seasar and Spring.
Swiftlet is a lightweight Web application framework written in PHP. It enables you to quickly deploy Web sites that are fast and secure. Swiftlet is extensible, flexible, and doesn't get in your way. Swiftlet requires zero configuration and has few conventions to which you must adhere. Swiftlet has all the features you would expect from a modern Web application framework. It implements the Model-View-Controller (MVC) architecture pattern to separate logic from design and takes advantage of the Object-Oriented Programming (OOP) capabilities of PHP 5.
