Research & Documentation 05 Php8
PHP New Version - Feature 1
Enums: PHP 8.1 introduced enumerations, allowing developers to define a set of named constants. This helps improve code readability and type safety, making it easier to work with fixed sets of values.
PHP New Version - Feature 2
Fibers: This feature provides lightweight concurrency support, enabling developers to pause and resume functions. Fibers can improve the performance of applications that require asynchronous programming patterns.
PHP New Version - Feature 3
Readonly Properties: PHP 8.1 allows properties to be declared as readonly, meaning they can only be written once, either during initialization or in the constructor. This enhances encapsulation and prevents accidental modifications.
Summary of the Documentation
PHP 8.0 introduced significant performance improvements, including the Just In Time (JIT) compiler, which enhances execution speed for certain types of code. It also added powerful new features such as union types, attributes (annotations), and match expressions, improving code clarity and functionality. With these enhancements, PHP 8 aims to streamline development and provide a more modern programming experience.
