PHP Microservices

By: Pablo Solar Vilariño, Carlos Pérez Sánchez

Overview of this book

The world is moving away from bulky, unreliable, and high-maintenance PHP applications, to small, easy-to-maintain and highly available microservices and the pressing need is for PHP developers to understand the criticalities in building effective microservices that scale at large. This book will be a reliable resource, and one that will help you to develop your skills and teach you techniques for building reliable microservices in PHP. The book begins with an introduction to the world of microservices, and quickly shows you how to set up a development environment and build a basic platform using Docker and Vagrant. You will then get into the different design aspects to be considered while building microservices in your favorite framework and you will explore topics such as testing, securing, and deploying microservices. You will also understand how to migrate a monolithic application to the microservice architecture while keeping scalability and best practices in mind. Furthermore you will get into a few important DevOps techniques that will help you progress on to more complex domains such as native cloud development, as well as some interesting design patterns. By the end of this book you will be able to develop applications based on microservices in an organized and efficient way. You will also gain the knowledge to transform any monolithic applications into microservices.

Preface

Debugging and profiling


Debugging and profiling is very necessary in the development of a complex and large application, so let’s explain what they are and how we can take advantage of these kinds of tools.

What is debugging?

Debugging is the process of identifying and fixing errors in programming. It is mainly a manual task in which developers need to use their imagination, intuition, and have a lot of patience.

Most of the time, it is necessary to include new instructions in the code to read the value of variables at a concrete point of execution or code to stop the execution in order to know whether it is passing through a function.

However, this process can be managed by the debugger. This is a tool or application that allows us to control the execution of our application in order to follow each executed instruction and find the bugs or errors, avoiding having to add code instructions in our code.

The debugger uses an instruction called breakpoint. A breakpoint is, as its name suggests, a...
