When a server has no PHP support enabled, it will either prompt to download a PHP file or may display it as HTML instead. When a user tries to run install.php with a server that does the latter, they will see some weird garbage with the browser trying to interpret raw PHP as HTML. This pathc adds a warning at the top, telling the user what is going on.

It seems this server has no PHP support enabled. You will need to
enable PHP before you can install and run DokuWiki. Contact your hosting
provider if you're unsure what this means.
