Building modern web applications using PHP

About this book:

Discover how to build professional, high-quality web applications with modern PHP in this comprehensive guide designed for developers ready to move beyond basic scripting. Whether you're new to backend development, transitioning from another language, or an experienced PHP programmer looking to update your skills, this book provides a practical roadmap to mastering the current PHP ecosystem. You'll learn how to leverage PHP 8+'s powerful features like strict typing, union types, and nullsafe operators while establishing a professional development environment with tools like Docker, Composer, and Xdebug that streamline your workflow from day one.

Progress through a carefully structured journey that builds your expertise from the ground up. Start with modern PHP fundamentals and advanced object-oriented programming concepts, then explore how design patterns and dependency injection create maintainable code. You'll gain hands-on experience building RESTful APIs with microframeworks, implementing secure user authentication with JWTs, and interacting with databases using both PDO and ORMs. Each chapter introduces essential professional practices—from writing effective unit and integration tests to implementing caching strategies that dramatically boost application performance.

Move beyond theory as you construct real-world features that power today's web applications. Learn to integrate frontend assets using modern build tools like Vite, implement real-time functionality with WebSockets, and connect to third-party services through secure API consumption. You'll master critical security techniques to protect against common threats like SQL injection and XSS, then discover how to containerize your application with Docker for consistent deployment across environments. The book also covers advanced topics including GraphQL API development, asynchronous PHP for high-concurrency scenarios, and serverless deployment options that represent the future of PHP hosting.

By the end of this guide, you'll possess the complete skill set needed to build scalable, secure, and professional PHP applications. You'll understand how to implement continuous integration and deployment pipelines that automate testing and delivery, apply horizontal scaling techniques to handle growing user bases, and make informed decisions about architectural choices ranging from traditional server setups to cutting-edge serverless platforms. Most importantly, you'll learn to think like a modern PHP developer—applying timeless software design principles while leveraging the language's mature ecosystem to create applications that are not just functional, but a pleasure to maintain and extend. This is your definitive guide to building with confidence in today's PHP landscape.

What You'll Find Inside:

• Modern PHP 8+ fundamentals including strict typing, union types, nullsafe operator, match expression, and named arguments for writing robust, type-safe code
• Professional development environment setup using Docker, Composer, modern IDEs (VS Code/PhpStorm), and essential command-line tools for efficient workflow
• Building RESTful APIs and microservices with microframeworks, covering routing, middleware, controllers, and dependency injection principles
• Dependency management with Composer and leveraging the PHP ecosystem through Packagist, PSR standards, and autoloading with PSR-4
• Comprehensive testing strategies (unit, integration, end-to-end) and CI/CD pipelines for reliable, automated deployment of PHP applications

Who's It For:

This book is designed for developers at various experience levels who want to build modern web applications with PHP. It's ideal for newcomers to web development curious about PHP's power, developers transitioning from languages like Python or JavaScript seeking to understand the modern PHP ecosystem, and experienced PHP developers looking to update their skills from legacy practices to contemporary standards. The book assumes basic programming knowledge but focuses on applying those concepts to build professional, secure, and scalable applications using PHP 8+ and its modern tooling.
