Overview of this book

PHP has always been the the go-to language for web based application development, but there are materials and resources you can refer to to see how it works. Data structures and algorithms help you to code and execute them effectively, cutting down on processing time significantly. If you want to explore data structures and algorithms in a practical way with real-life projects, then this book is for you. The book begins by introducing you to data structures and algorithms and how to solve a problem from beginning to end using them. Once you are well aware of the basics, it covers the core aspects like arrays, listed lists, stacks and queues. It will take you through several methods of finding efficient algorithms and show you which ones you should implement in each scenario. In addition to this, you will explore the possibilities of functional data structures using PHP and go through advanced algorithms and graphs as well as dynamic programming. By the end, you will be confident enough to tackle both basic and advanced data structures, understand how they work, and know when to use them in your day-to-day work

Understanding functional programming with PHP

Unlike any object-oriented programming language where everything is represented through an object, functional programming starts thinking everything in terms of functions. OOP and FP are not mutually exclusive. While OOP focuses on code maintainability and reusability by encapsulation and inheritance, functional programming, unlike state-oriented imperative programming, is focused on value-oriented programming, which considers computation as a pure mathematical evaluation and avoids mutability and state modification. When working with OOP, one of the challenges is that the object we have created can bring many extra properties or methods along with it whether or not we are using it in a particular case. Here are the three key characteristics of functional programming:

  • Immutability
  • Pure functions and referential transparency
  • First...
