PHP 7.0: Significant performance improvements, support for scalar types (int, float, bool, string), return type declarations, the spaceship operator (<=>), anonymous classes.
PHP 7.1: Nullable types, support for the void keyword for functions, improvements in generator handling.
PHP 7.2: Support for objects as parameter types, security enhancements, new functions and extensions.
PHP 7.3 and 7.4: Arrow functions, class property types, spread operator for arrays, syntax improvements.
