What You'll Learn in This Book
- Master PHP 8.x Fundamentals: Understand the evolution of PHP, why PHP 8.x is a game-changer, and how to set up your optimal development environment, including Docker, Xdebug 3, and Composer.
- Deep Dive into PHP 8.0 Features:
- Harness the power of the JIT compiler for significant performance gains, learning how it works, when to use it, and how to benchmark its impact.
- Implement Attributes (annotations) for cleaner metadata in your code, from framework integration to validation and API documentation.
- Leverage Union Types for more expressive and robust type hinting, improving code clarity and static analysis.
- Replace switch statements with the more powerful and concise match expression.
- Streamline your code with the nullsafe operator (?->), eliminating "Christmas tree" null checks.
- Enhance code readability and maintainability using Named Arguments.
- Reduce boilerplate with Constructor Property Promotion.
- Explore other key PHP 8.0 enhancements like the static return type, mixed type, and new string functions.
- Explore PHP 8.1 Innovations:
- Utilize Enumerations (Enums) for type-safe constants and improved code organization.
- Understand Fibers to build concurrent and asynchronous PHP applications, opening doors to non-blocking I/O and cooperative multitasking.
- Enforce immutability with Readonly Properties for more reliable objects like Value Objects and DTOs.
- Combine multiple type constraints effectively with Intersection Types.
- Declare functions that never return using the never return type for better static analysis.
- Prevent overriding of class constants with final class constants.
- Discover new functions like array_is_list() and first-class callable syntax.
- Unveil PHP 8.2 Advancements:
- Extend immutability to entire classes with Readonly Classes.
- Solve complex type hinting scenarios using Disjunctive Normal Form (DNF) Types.
- Use null, false, and true as standalone types for precise type declarations.
- Understand the deprecation of Dynamic Properties and how to adapt your codebase using the #[AllowDynamicProperties] attribute.
- Learn about the new Random Extension and how to redact sensitive parameter values with #[SensitiveParameter].
- Discover What's New in PHP 8.3:
- Add robust type declarations to Typed Class Constants.
- Explicitly mark overridden methods with the #[Override] attribute for safer refactoring.
- Handle deep-cloning of readonly properties correctly.
- Efficiently validate JSON strings with the new json_validate() function.
- Optimize and Modernize Your PHP Applications:
- Master performance benchmarking and optimization techniques in PHP 8.x, including leveraging the JIT, Opcache, and profiling tools like Xdebug and Blackfire.io.
- Adopt modern PHP best practices, including PSR standards, SOLID principles, and design patterns.
- Learn best practices for error handling, logging, security, and writing testable code with PHPUnit.
- Migrate legacy code to PHP 8.x efficiently, identifying breaking changes and using tools like Rector for automated upgrades.
- Gain insights into the future of PHP, including upcoming features and community resources.
