The PHP development team has announced the immediate availability of the much anticipated PHP 7.0.0, which brings PHP to version 7, coming from version 5. PHP 7.0.0 comes with a wide array of new features and also includes a new version of the Zend Engine.
Some of the new features and improvements include improved performance (up to 2X and smaller memory footprint), consistent 64-bit support, a new null coalescing operator, and scalar type declarations. For a more exhaustive list of the news in PHP 7.0.0, please refer to the release announcement.
Almost two years of development has preceded the release of PHP 7, and this release is the beginning of a new generation of PHP.
