Overview of this book

Phalcon is a high-performance PHP framework delivered as a PHP extension. This provides new opportunities for speed and application design, which until recently have been unrealized in the PHP ecosystem. Packed with simple learning exercises, technology prototypes, and real-world usable code, this book will guide you from the beginner and setup stage all the way to advanced usage. You will learn how to avoid niche pitfalls, how to use the command-line developer tools, how to integrate with new web standards, as well as how to set up and customize the MVC application structure. You will see how Phalcon can be used to quickly set up a single file web application as well as a complex multi-module application suitable for long-term projects. Some of the recipes focus on abstract concepts that are vital to get a deep comprehension of Phalcon and others are designed as a vehicle to deliver real-world usable classes and code snippets to solve advanced problems. You’ll start out with basic setup and application structure and then move onto the Phalcon MVC and routing implementation, the power of the ORM and Phalcon Query Language, and Phalcon’s own Volt templating system. Finally, you will move on to caching, security, and optimization.

Creating your own Volt keywords and methods


The Volt Template Engine is quite flexible and can be extended by adding user functions, as well as keywords to the existing ones. In the first part of this recipe, we will add a user extension which will let you use practically any PHP function in Volt, and then we will register a new function, adding a new feature to Volt Template Engine.

Getting ready

For successful implementation of this recipe, you need to have an application with the configured Volt Template Engine service. In our example, we will use a template application generated by means of the Phalcon Developer Tools, however, you can use any other application that you have set.

How to do it…

Follow these steps to complete this recipe:

  1. Create the PhpExtension extension and add the following code in it:

    <?php
    
    class PhpExtension
    {
        public function compileFunction($name, $args = null)
        {
            if (function_exists($name)) {
                if (func_num_args() > 1) {
                  ...
