Mastering PHP Design Patterns

By: Junade Ali

Overview of this book

Design patterns are a clever way to solve common architectural issues that arise during software development. With an increase in demand for enhanced programming techniques and the versatile nature of PHP, a deep understanding of PHP design patterns is critical to achieve efficiency while coding. This comprehensive guide will show you how to achieve better organization structure over your code through learning common methodologies to solve architectural problems. You’ll also learn about the new functionalities that PHP 7 has to offer. Starting with a brief introduction to design patterns, you quickly dive deep into the three main architectural patterns: Creational, Behavioral, and Structural popularly known as the Gang of Four patterns. Over the course of the book, you will get a deep understanding of object creation mechanisms, advanced techniques that address issues concerned with linking objects together, and improved methods to access your code. You will also learn about Anti-Patterns and the best methodologies to adopt when building a PHP 7 application. With a concluding chapter on best practices, this book is a complete guide that will equip you to utilize design patterns in PHP 7 to achieve maximum productivity, ensuring an enhanced software development experience.

Cronjob imitating service


This one is a personal hatred of mine. A developer needs a service to run indefinitely, so they just enable a cronjob that never ends, or simply have a cronjob that operates incredibly frequently (such as once every few seconds).

A cronjob is a scheduled job that will run at a predetermined time. It's not something that operates services for you. Not only is this messy from an architectural perspective, but it scales horribly and becomes terrible to monitor.

A constantly processing task should be treated as a daemon and not as something that runs on the basis of a cronjob.

Monit is a tool in Linux systems that allows you to imitate services.

You can install Monit using the apt-get command:

sudo apt-get install monit

Once Monit is installed, you can add processes to its configuration file:

sudo nano /etc/monit/monitrc

Monit can then be started by running the monit command. It also has a status command so you can verify it is still running:

monitmonit status

You can...
