PHP 7 comes with a new version of the Zend Engine with numerous improvements. This is the most important change for PHP since the release of PHP 5 in 2004, bringing explosive performance improvements, drastically reduced memory consumption, and a host of brand-new language features to make your apps soar.
Thanks to the new Zend Engine 3.0, your apps see up to 2x faster performance and 50% better memory consumption than PHP 5.6, allowing you to serve more concurrent users without adding any hardware. Designed and refactored for today’s workloads, PHP 7 is the ultimate choice for web developers today.
