obviously, client's language preferences first step, won't in cases. if return value, not use determine appropriate currency described - users may set preferred language/region foreign setting. examples expats , language learners. though may edge case, don't trust detect currency.

the robust solution use geolocation service returns currency location found, e.g. http://www.geoplugin.com/webservices/php.

the combination of both methods may solution. if return conflicting values, offer user possibility choose 2 found currencies (or other).
