This is a quote from Jeff Atwood (founder of Stackflow) about PHP (he's not a fan):
Despite the serious problems with PHP, I was forced to consider it. If you want to produce free-as-in-whatever code that runs on virtually every server in the world with zero friction or configuration hassles, PHP is damn near your only option. [1]
When did Atwood say this? 2012.
A decade has passed and hardly anything has changed. Server installation remains needlessly complicated. Current solutions like Docker, Sandstorm, Cloudron, command line scripts etc. are "easy" for developers but not for ordinary users. What is easy for ordinary users? Installing a web app by uploading files to a folder on a server using a GUI FTP app is one example for PHP. (And for some non-technical users, even that might be too complicated).
