php - International Domain Names -

-

when navigate aртем.example.com, web browser convert url xn--a-jtbvok.example.com. there way convert xn--a-jtbvok aртем using php?

currently using $_server['http_host'] fetch requested url.

live examples here: aртем.lekintepls.se , åäö.lekintepls.se.

i have no idea phenomena called, i'm sorry if duplicate.

this notation called punycode or idna (internationalizing domain names in applications).

you can use idn_to_utf8 , idn_to_ascii convert between 2 notations.
