Câu trả lời What are some of the big changes PHP has gone through in the past few years?
PHP has undergone several major changes and improvements in recent years:
PHP 7 (2015)
PHP 7, released in 2015, brought significant performance improvements and new features:
It introduced a new PHP branch called phpng which aimed to optimize PHP performance by refactoring the Zend Engine while retaining near-complete language compatibility. Benchmarks showed an almost 100% increase in performance[1].
Many fatal or recoverable-level legacy PHP error mechanisms were replaced with modern object-oriented exceptions[1].
It introduced return type declarations for functions which complement the existing parameter type declarations, and support for scalar types (integer, float, string, and boolean) in parameter and return type declarations[1].
PHP 8 (2020)
PHP 8, released in 2020, included even more improvements and new features:
It introduced a just-in-time (JIT) compiler which can provide additional performance improvements in certain cases[1].
It added named arguments, which allow arguments to be specified by name instead of relying on strict order[1].
It introduced union types, which allow a parameter or return value to be declared as having one of multiple types[1].
