The final version of PHP 7 is available for download on Github and the PHP mirrors now. PHP7 is the next generation of the PHP programming language, it is up to 2 times faster than PHP 5.6 and 14 times faster than PHP 5.0 according to the release notes. The new PHP version is not 100% compatible with PHP 5.x as some deprecated API’s have been removed, so it is a good idea to start testing your web sites for compatibility with this new release. This can be done easily and without affecting all sites on your server by using the multi PHP version feature in ISPConfig 3. The PHP version can be selected in the ISPConfig 3 website settings for each site individually. This feature works with PHP-FPM and FastCGI. This tutorial shows how to build the new PHP 7 as a PHP-FPM and a FastCGI version on a Debian Jessie server. These PHP 7 builds include Zend OPcache.
