Today, we’re pleased to announce that PHP 7.0 – the fastest and most efficient PHP ever – is officially released!
PHP 7.0 brings you unprecedented levels of real-world performance and throughput by utilizing the new and advanced Zend Engine 3.0, designed and refactored for speed and reduced memory consumption.
