PHP 7: Real World Application Development. Real World Application Development
Doug Bierer, Iltaf (Altaf) Hussain Gul, Branko...
PHP is a great language for developing web applications. It is essentially a server-side scripting language. PHP 7 is the latest version, providing major backward-compatibility breaks and focusing on improved performance and speed. This course follows a learning path which is divided into three modules. Each module is a mini course in its own right, taking your basic PHP programing skills to the next level by showing you intermediate to advanced PHP techniques with a focus on PHP 7. The first module of the book is a programming cookbook that consists over 80 recipes! Each recipe is designed to solve practical, real-world problems faced by PHP developers like yourself every day. This course also covers new ways of writing PHP code made possible only in version 7. The second module of the course is designed to improve the performance and productivity of your application. You’ll be introduced to the concepts of Object-Oriented Programming (OOP) in PHP 7 and then shed some light on how to improve the performance of your PHP 7 applications and database. With all important concepts of PHP covered up you will move on to third module. In this module you will gain a deep insight into the modular programming paradigm and how to achieve modularity in your PHP code. Modular design techniques help you build readable, manageable, reusable, and more efficient codes. By the end of this module you will have a good understanding of modular application development using PHP 7.This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products:• PHP 7 Programming Cookbook, Doug Bierer• Learning PHP 7 High Performance, Altaf Hussain• Modular Programming with PHP 7, Branko Ajzele

Most successful Ruby applications become more difficult to maintain as the codebase grows in size. Polished Ruby Programming, 2nd Edition provides you with the skills and advice you need to design Ruby programs and libraries that are robust, performant, scalable, and maintainable.The book takes you through possible implementation approaches for many common programming situations, discusses the trade-offs inherent in each approach, and explains why you may sometimes choose to use different approaches. You'll start by learning fundamental Ruby programming principles, such as correctly using core classes, class and method design, variable usage, error handling, and code formatting. Then you’ll move on to higher-level topics such as library design, metaprogramming, domain-specific languages, and refactoring. Finally, you'll learn about the pros and cons of different approaches to concurrency, what you should consider when deciding whether to use static types in your Ruby code, and how best to optimize your Ruby code.The 2nd edition of Polished Ruby Programming has been updated to include relevant changes between Ruby 3.0 and 3.5. While most principles discussed in the book apply to all recent Ruby versions, some of the content in the book is specific to Ruby 3.5, the latest release at the time of publication.
