why joomdle wiki is not update? it is for joomdle 1.1.3
www.joomdle.com/wiki/Prerequisites

i need server requirement tips

Thanks for the heads up, I updated the docs with newer version.

As for PHP version: Joomdle does not care. You need to check PHP versions supported by the Joomla and Moodle versions you want to use.
That said: php 5.6 is almost deprecated and you should not use it for any new projects.
