Just tried to make my own config handler in PHP, utilizing the native PHP
I guess the most simple solution to the problem is to just use your own config handler. Either write a ini class or download a free one (ini format is extremely simple).
But I would recommend storing your config in xml if you want interoperability. Every modern programming language has tons of XML parsers available or build-in. Also you gain more flexibility in your settings structure. And you can easily make you settings format typesafe.
