On December 3, PHP released its latest version: PHP 7. The version before, PHP 5.6 was already a year old.
This new version of PHP is a major step for the programming language. It offers a good number of improvements and optimizations that are the results of a more than 2 years of work. Some people in the industry even called this new version a new generation of PHP, with great potential.
PHP 7 is also up to twice faster than PHP 5.6, and it uses up to twice less memory.
Please make sure your set up is compatible with PHP7 before activating it.
