This question already has an answer here:
I have a div with an img tag. This img tag should display the visitors country flag. However, im getting no progress in trying to find a solution.
A first thought was maybe those things are possible via server side and php, but then I again there must be a simple jquery method.
I am not asking anyone to code a solution! I just want to know what methods are there for simple tasks like mine? I also tried to look for libraries that do that without the so called "JSON".
</div>
You can do that using the geolocation API. But the user has to allow the location detection for it to work.
https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation
HTML5 provides a Geolocation API, maybe you can try to use that.
https://developers.google.com/maps/documentation/javascript/examples/map-geolocation?hl=de
Google (and maybe other too) offers a free API to transform the location to for example the country.
Unfortunately this is a bit of a link only answer, but you have a similar question here:

How can I get user's country flag on my site
According to this link you can also use $_SERVER['HTTP_ACCEPT_LANGUAGE'] to get the language, rather than using a third part service.
