Huh? This particular bug has everything to do with PHP. PHP is reasonably unique in the model of “treat everything like a standard webserver serving up files from the filesystem, except they’re PHP scripts/templates that get evaluated to produce content, vs a true static file.” But misconfigure your web server, and it’ll just serve up the source code instead. This wouldn’t happen in almost any other language.
