 I prefer this new function rather than the old one because it is more precise in parsing the browser acceptable languages and because it either returns a language found by match or the default language. Although it seems the former code was also fixed to return the same results. It also doesn't convert the HTTP_ACCEPT_LANGUAGE to lowercase, which I didn't see as necessary. -- 2004.11.03.

 Please post your comment about "A Improved Using of the top Tip" below.
+I think there are two goals with the above - one appears to be allow for translation and the other is simply to provide a per-user localised interface for the users of dokuwiki.
+I want the latter function and I achieved it by using the detect_browser_language() function above. I placed it in inc/init.php
+I then hacked init_lang (in init.php). I haven't really used dokuwiki before so please can someone let me know a better place to "hack" this browser language override.
+<code>
+function init_lang($langCode) {
+    //prepare language array
+    global $lang, $config_cascade;
+    $lang = array();
+    $langCode = detect_browser_language();   // HACK this line in to override language setting with browser language
+    //load the language files
+    require(DOKU_INC.'inc/lang/en/lang.php');
+    foreach ($config_cascade['lang']['core'] as $config_file) {
+        if (@file_exists($config_file . 'en/lang.php')) {
+            include($config_file . 'en/lang.php');
+        }
+    }
+    if ($langCode && $langCode != 'en') {
+        if (file_exists(DOKU_INC."inc/lang/$langCode/lang.php")) {
+            require(DOKU_INC."inc/lang/$langCode/lang.php");
+        }
+        foreach ($config_cascade['lang']['core'] as $config_file) {
+            if (@file_exists($config_file . "$langCode/lang.php")) {
