<?php
function get_client_language($availableLanguages, $default='en'){
    if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
        $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);

        foreach ($langs as $value){
            $choice=substr($value,0,2);
            if(in_array($choice, $availableLanguages)){
                return $choice;
            }
        }
