In Detail

Phalcon is a full-stack PHP framework implemented as a C extension. Building applications with Phalcon will offer you lower resource consumption and high performance whether your application runs on a Linux machine or a Windows one. Phalcon is loosely coupled, allowing you to use its objects as glue components based on the needs of your application. Phalcon PHP's mission is to give you an advanced tool to develop faster websites and applications.

This book covers the most common and useful parts of PhalconPHP, which will guide you to make the right decisions while developing a Phalcon-driven application.

You will begin the journey by installing and setting up Phalcon for your environment followed by the development of each module. You will be introduced to Phalcon's ORM and ODM. Furthermore, you will also be able to create the first models and database architecture for your project. You will then cover command-line applications, API module, volt syntax, and hierarchical views. Installing and working with Node and Bower for assets management will also be covered. Finally, you will gain insights into creating the backoffice and frontend module along with best practices and resources for development with Phalcon PHP.

By the end of this book, you will be able to confidently develop any kind of application using the Phalcon PHP framework in a short time.

Style and approach

This step-by-step guide will walk you through the fundamentals of Phalcon PHP. It will then help you to create a simple but fully functional news website and gain advanced knowledge of how Phalcon PHP works.
