PHP 7 is the first major update in over a decade and provides an impressive increase in performance — it is twice as fast as the current version, 5.6. (Note: PHP 6 was not released, so version 5.6 is followed by version 7).
BENEFITS OF USING PHP 7
PHP7 has many benefits over PHP5.6. While features such as new spaceship and null coalescing operators may only be meaningful to developers, here are the real benefits for your website:
- Speed – sites load faster, which benefits visitors to your site as well as your Google ranking
- Uses less memory – which is particularly useful for mobile friendly applications
- Enables more concurrent connections – up to twice as many requests per second
