[pabrigarcia]

Estoy haciendo una web en varios 3 idiomas español,chino e italiano y la quiero redireccionar detectando el idioma del navegador

se que para españa es "es" ¿para el italiano es "it"?

El php ya lo tengo programado pero me falta saber las extensiones que no la se y en el buscador no encuentro nada
Alguien me puede decir para el italiano y el chino que extension hay que poner para detectar el idioma del navegador?
