While DokuWiki on a Stick
https://www.dokuwiki.org/install:dokuwiki_on_a_stick is nice for testing, I wonder if there is any easy chance to update it's components. Especially it's PHP Version.
For example, I'd like to test the struct Plugin
https://www.dokuwiki.org/plugin:struct, but it requires PHP 5.6 or higher. The DokuWiki on a Stick bundle contains Apache/2.4.7 with PHP/5.4.25.
