• Beginner PHP developers who want to avoid common pitfalls.
• Experienced programmers looking to systematize knowledge and implement best practices.
• Those transitioning to PHP from other languages and wanting to quickly master its specifics.
• Team leads and architects wishing to establish code standards within the team.

Each chapter contains not only explanations but also ready-made code snippets that can be immediately applied in a project. The author shares personal experience, analyzes real-world cases from commercial development, and shows how to turn "just working code" into a professional solution.

The book is written in a lively language, without excessive academicism, and will be useful both for self-study and as a desktop reference. After reading it, you will be able to confidently develop complex web applications that are easy to maintain and evolve.
