This is a tutorial on how to get PhalconPHP to work with PHP7 , even if its still in dev mode its a good starting point ;)
PHP7 was released on the 3rd of December, 2015. This new version brought forward a large number of new and exiting features (https://php.net/manual/en/migration70.new-features.php) to PHP. Perhaps one of the biggest of the new features is a new Zend Engine (the engine that powers PHP).
