PHP Get browser Language

In php you can get the language of your visitor, this is very helpful if you have many versions of your website for different languages.

You can get the language of your visitor in this way:

<?php
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
?>

This will give you the 2letter language code, ie: en for english and fr for french .

In fact $_SERVER['HTTP_ACCEPT_LANGUAGE'] will get all language the user prefer to use, in order. So substr() will give you the first choice, you can also get the second choice, the third ...

Having the language of your visitor will let you display custom page depending on his language, for example if someone's language is french, you will have $lang="fr" , then you can redirect him to www.yoursite.com/fr/ or yoursite.com/?lang=fr to show him your website in french, or show him things related to french language, whatever your website is about.
