Overview of this book

Are you a PHP developer looking to take your first steps into the world of Ruby development? From PHP to Ruby on Rails will help you leverage your existing knowledge to gain expertise in Ruby on Rails. With a focus on bridging the gap between PHP and Ruby, this guide will help you develop the Ruby mindset, set up your local environment, grasp the syntax, master scripting, explore popular Ruby frameworks, and find out about libraries and gems. This book offers a unique take on Ruby from the perspective of a seasoned PHP developer who initially refused to learn other technologies, but never looked back after taking the leap. As such, it teaches with a language-agnostic approach that will help you feel at home in any programming language without learning everything from scratch. This approach will help you avoid common mistakes such as writing Ruby as if it were PHP and increase your understanding of the programming ecosystem as a whole. By the end of this book, you'll have gained a solid understanding of Ruby, its ecosystem, and how it compares to PHP, enabling you to build robust and scalable applications using Ruby on Rails.

One of the first things we need to learn about when picking up Ruby is how to run our code and view the output directly on our screen. There are different ways to achieve this, but we will be doing so in the simplest of ways. While there are various ways to load code from the command line, we’ll start with one single file.

Running a simple code file

As I mentioned in the introduction, running scripts in Ruby is simple and easy. Similar to running scripts in PHP, we can create a file, add Ruby code to it, and execute it with Ruby. Running or executing code simply means that we will have Ruby read (also referred to as parse) through our source code, and then translate it into a language that the computer can understand and process.

Let’s start with a simple example by creating a folder called ruby_syntax on our desktop. In that folder, create our source code file, which is called running_ruby.rb, with your IDE of choice.
