PHP 8 is the latest release of the PHP programming language that brings several exciting new PHP features and improvements that can help developers create more robust and efficient applications. This version of PHP has been in development for over two years. It consists of a wide range of enhancements and optimizations that make it one of the most advanced programming languages available today.
One of the most impressive PHP 8 new features is the introduction of JIT (Just-In-Time) compilation, which can significantly enhance the performance of PHP applications by compiling code at runtime. Other new features are named arguments, union types, match expressions, improvements to the error-handling system and so on.
Speed comparison is also an essential characteristic of PHP 8. With the introduction of the JIT compilation, PHP 8 can provide significant performance advancements over previous language versions. This means that applications can run quickly and handle more requests simultaneously, which leads to a better user experience and higher scalability.
