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.

Some decades ago, one of the few options (if not the only option) for saving information was storing it in files. All sort of data was stored in these files: passwords, user data, config data, and more. Saving information in plain text files was, at the time, the most feasible option to save information. It all came to an end with the advent of databases (DBs) and DB usage. DBs became a more feasible and popular option, and they now came in different flavors. While this is still true today, using a DB comes with a quite expensive cost. I’m not only talking about a monetary cost – I’m talking about it in terms of memory, disk, and processing time. So, in certain use cases, it’s still a much better option to use plain text files to store information. To that purpose, most programming languages, including Ruby and PHP, make this task straightforward. Let’s take a look at how we can take advantage of the file manipulation tooling that...
