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.

Handling abnormal terminations


It is essential that applications have a means of handling abnormal conditions without hard crashing. In this recipe, we will create a dispatcher plugin that will handle two specific types of exceptional behavior. The first one will allow us to handle HTTP 404 conditions, and the second will allow us to catch any exception that occurs in the dispatcher cycle and display a specific page notifying that an error has occurred. So, by adding this functionality, we will prevent our users from seeing a white screen of death.

Getting ready

This recipe uses Phalcon Developer Tools which we will use to set up a project skeleton and database access is not required.

How to do it…

Follow these steps to complete this recipe:

  1. We need to have an application skeleton for experimentation. If you already have such an application, you can skip this step. Create a project skeleton using the simple template:

    phalcon project abnormal_termination simple
  2. Now point the web browser at the root...
