Algorithms and Data Structures in PHP: From Beginner to Pro

The book "Algorithms and Data Structures in PHP" is a practical guide that will help you master the fundamental concepts of computer science through the lens of the PHP language. Whether you are just starting your journey in programming or already have work experience, this book will become your reliable assistant in creating efficient and performant code.

What is this book about?

The book thoroughly covers all key algorithms and data structures necessary for professional PHP development. You will learn how to correctly choose and implement data structures, optimize algorithms, and avoid common mistakes. Each topic is accompanied by clear code examples that can be immediately applied in real projects.

Who is this book for?

• Beginner PHP developers — gain a solid foundation that will allow you to write quality code from day one.
• Experienced programmers — systematize your knowledge, learn new approaches to optimization and solving complex problems.
• Students and teachers — an excellent study guide with practical tasks and analysis of real-world cases.
• Interview candidates — prepare for algorithm and data structure questions commonly asked in IT companies.

What will you learn from the book?

• Basic data structures: arrays, lists, stacks, queues, hash tables, trees, and graphs — their implementation and usage specifics in PHP.
• Sorting and search algorithms: from bubble sort to quicksort, binary search, depth-first and breadth-first search.
• Performance optimization: how to measure algorithm complexity (Big O), find bottlenecks, and speed up application performance.
• Working with graphs: Dijkstra's algorithm, Bellman-Ford algorithm, topological sorting, and their application in real projects.
• Dynamic programming: solving complex problems by breaking them down into subproblems.
• Practical examples: implementing search engines, recommendation algorithms, and processing large data sets.

Why choose this book?

Unlike many abstract textbooks, this book is specifically tailored for PHP developers. All examples are written in modern PHP (8.x) and take into account the language's specifics: weak typing, memory management, and built-in functions. You will not only study theory but also learn to apply algorithms in real web applications, frameworks (Laravel, Symfony), and when working with databases.

The book contains over 50 practical tasks with solutions to help reinforce the material. Each chapter concludes with a summary and review questions for self-assessment. After reading, you will be able to confidently pass technical interviews and write code that runs quickly and efficiently.
