php - Change language directory without redirecting to the index page -

i have site in 3 languages:

 www.mysite.com/it/files  www.mysite.com/de/files  www.mysite.com/fr/files 

on header of site have 3 link, 1 each language. each link redirect to

/language/index.php 

i'd redirect user current page watching in new language.

i tried with

__file__ 

or

dirname 

but didn't reach that!

thank you!

try in page load:

$prefix = $_server['http_host']; $file = explode('/', $_server['php_self']); $page = $file[count($file)-1];  if (file_exists($prefix.'/it/'.$page)) {     http_redirect($prefix.'/it/'.$page); // italian }  if (file_exists($prefix.'/de/'.$page)) {     http_redirect($prefix.'/de/'.$page); // german }  if (file_exists($prefix.'/fr/'.$page)) {     http_redirect($prefix.'/fr/'.$page); // french } 

in javascript (jquery click example) this:

var host = document.location.hostname; var path = window.location.href; var filename = path.replace(/^.*[\\\/]/, '');  $('.myitalianlink').click(function(){     window.location.href = host + '/it/' + filename; // italian });  console.log(host + '/it/' + filename); 

outputs:

http://www.mywebsite.com/it/html4.php 

the javascript approach more suiting needs, it's more reactive in case of user interaction (the links named).
