PHP 7 Officially Made Available
PHP (Personal Home Page/Hypertext Preprocessor) is known as the fourth most popular programming language in the world, powering more than 200 million Websites, with more than 81.7 percent of public websites leveraging PHP on the server side.
This week PHP introduced its the first major update to the language since 2004, when version 5.0 was released.
The main feature of PHP 7 is massively improved performance. Compared to Wordpress running PHP 5.6, performance has significantly improved three times.
It also features other smaller changes, such as significantly reduced memory usage, return type declarations, the spaceship operator and more.
PHP 7 contains a number of breaking changes, such as the removal of PHP safe mode, magic quotes, a number of new reserved keywords and others.
This would mean that WordPress needs to be partially re-engineered in order to be ready for PHP 7’s release, though it appears it’s now fully compatible with the upgrade.
However, it's availability doesn't mean that everything would need to change. It’s global adoption many take a number of years. Web applications, particularly within the enterprise, tend to take years to upgrade to new platform versions. But with the sizable performance improvements, Web developers will be tempted to upgrade much sooner.
