How to Hide PHP Version on Synology NAS

Your Synology security must be the first thing on your mind, especially when you are using Synology NAS as a web server. WordPress is the basis for building a website, and hosting it from home with Synology has never been easier than this. There are websites on the web, like “Sucuri“, that offer free website scans. They can reveal your current PHP version you are using on your Synology. I honestly don’t like being spied on and I don’t like these sites revealing my PHP version. Privacy is extremely important. Fortunately, there is a simple way to hide your PHP version on Synology, irrespective if it’s PHP 8, PHP 7.3, PHP 7.4 or another PHP version. Follow the step by step guide below.
