Here is how you can quickly update PHP 7.0 to 7.1 on a Vultr Ubuntu domain.
Advertisement:
I have configured a number of Vultr domains with NGINX and PHP 7.1 FPM and today I realised I need to update PHP 7.0 to 7.1 to fix a few security exploits (read more here and here on securing Ubuntu in the cloud). PHP has a good page where you can keep up to date with PHP news here https://secure.php.net/. You can also view the PHP bug tracker to view bugs here. PHP aggregation user @php_net on twitter is good to follow, the official PHP twitter account is @official_php.
I have not noticed in daily Ubuntu package updates no option to update PHP 7.0 to 7.1, I must have to update manually.
WARNING: Backup your site and test this on a non production server before doing it on a live server. I had an issue with PHP 7.1 breaking WordPress 3.9 (mysql issues with some plugins) and I had to roll back to 7.0 (see rollback tips in troubleshooting below). WordPress says it is PHP 7.1 compatible but issues exist. WordPress 3.9 ditches “mysql” and used “mysqli” and when instead PHP 7.1 WordPress could not find “mysqli”?
