For the early adopters out there, PHP 7.3 is now available across all of our servers.
PHP 7.3 builds upon the great improvements brought forward in PHP 7 and introduces several new features for developers which you can read about at: http://php.net/manual/en/migration73.php
To change your PHP version, simply log into your cPanel and follow this guide: https://varialhosting.com/support/faq/hosting/#changephp
Please be aware that not all web applications and PHP extensions are compatible with PHP 7.3 at this time. For best compatibility we recommend using PHP 5.6 or 7.2 until development of PHP 7.3 matures.
