Yii
Yii PHP framework
Yii is a fast, secure, and efficient PHP framework. Flexible yet pragmatic, works right out of the box, and has reasonable defaults. While Yii can virtually eliminate most repetitive coding tasks, you are responsible for the real creative work. This often starts with designing the whole system to be built, in terms of some database schema. The best way to do this is by using migrations. Yii gives you the maximum functionality by adding the least possible overhead. Sane defaults and built-in tools help you write solid and secure code. Write more code in less time with simple, yet powerful APIs and code generation. Yii is a generic web programming framework, meaning that it can be used for developing all kinds of web applications using PHP. Because of its component-based architecture and sophisticated caching support, it is especially suitable for developing large-scale applications such as portals, forums, content management systems (CMS), ecommerce projects, RESTful services, etc.Starting Price: Free -

Zephir/C extensions are loaded together with PHP one time on the web server's daemon start process. Classes and functions provided by the extension are ready to use for any application. The code is compiled and isn't interpreted because it's already compiled to a specific platform and processor. Thanks to its low-level architecture and optimizations Phalcon provides the lowest overhead for MVC-based applications. Build single and multi-module applications with ease and pleasure. Using the file structure, scheme, and patterns you already know. Writing REST servers and applications has never been easier, with no boilerplate, and simple services that fit in one file.Starting Price: Free -

FuelPHP
FuelPHP
The Fuel PHP framework is a fast, simple, and flexible PHP 5.4+ framework, born from the best ideas of other frameworks, with a fresh start. It was born out of the frustrations people have with the currently available frameworks and developed with support from a community of developers. FuelPHP is extremely portable, works on almost any server, and prides itself on clean syntax. FuelPHP is an MVC (Model View Controller) framework that was designed from the ground up to have full support for HMVC as part of its architecture. But we didn't stop there, we also added ViewModels (also known as presentation models) into the mix which gives you the option to add a powerful layer between the controller and the view. FuelPHP also supports a more router-based approach where you might route directly to a closure which deals with the input URI, making the closure the controller and giving it control of further execution.Starting Price: Free -
