PHP 7 brings a plethora of features enhancing development efficiency. Scalar type-hints expand type-hinting to include integers, floats, booleans, and strings, enhancing input consistency. Anonymous classes offer simplicity for one-off objects, while Closure::call() simplifies callback execution. Generator delegation enables addressing generators from other functions, and generator return expressions allow for return values in generators. The null coalesce operator streamlines value checks, and the space ship operator facilitates value comparisons. Notably, PHP 7 adopts Throwable interface for errors, improving error handling. Additionally, improvements like level support for dirname() and intdiv() function add to the language’s usability. Overall, PHP 7 boasts impressive performance enhancements, outperforming even HHVM.
