Requirements Checker
You will need PHP version 7.2 or higher to run Nette Framework 3.1. Also, your server will have to comply with required configuration of PHP.
Requirements Checker is tool bundled with application example known as Sandbox, which checks server configuration and tells you, whether you can use this framework or not.
You can download Nette Framework manually (package contains Sandbox), but the recommended way is to use Composer:
composer create-project nette/sandbox
Requirements Checker is located in folder /checker of Sandbox, so type URL to web browser i.e.
http://localhost/sandbox/www/checker. Now you will find if your server meets minimal requirements.
Green message with “Congratulations!” is self explaining tells if you can use Nette right away!
