Problem whit my pages

[Poushaft]

I have a problem whit my script in my pages. I have a multiple language ( French / English) in my page.
I call this tag in my index.php.

<?php
require("../shared/lang/incl-lang.php")
?>

And in my page incl-lang.php i have this code.

<?php

if(isset($HTTP_COOKIE_VARS['lang'])) { 
    $lang = $HTTP_COOKIE_VARS['lang']; 
} else {
    $lang = substr($HTTP_SERVER_VARS['HTTP_ACCEPT_LANGUAGE'],0,2);
}

if ($lang=='fr') {
  include('../shared/lang/fr-lang.php');

} else if ($lang=='en') {
  include('../shared/lang/en-lang.php'); 
}

$expire = 365*24*3600;

setcookie("lang",$lang,time()+$expire);

?>

The problem is when the cookie is written i'am not able to change my language whit the url.

http://mysite.com/index.php?lang=en
or
http://mysite.com/index.php?lang=fr

Because the code take my cookie value before.

If someone see my error or know another way to make this php project work please tell me.

<?php

if ( $HTTP_POST_VARS['lang'] )  // if we have an url with the lang
{
$lang = $HTTP_POST_VARS['lang'];
}
else // if we do not have an url with the lang
{

if(isset($HTTP_COOKIE_VARS['lang'])) { 
    $lang = $HTTP_COOKIE_VARS['lang']; 
} else {
    $lang = substr($HTTP_SERVER_VARS['HTTP_ACCEPT_LANGUAGE'],0,2);
}

}

// Include the language now

if ($lang=='fr') {
  include('../shared/lang/fr-lang.php');

} else if ($lang=='en') {
  include('../shared/lang/en-lang.php'); 
}

$expire = 365*24*3600;

setcookie("lang",$lang,time()+$expire);

?>

when i read your reply i think is you cod eis a good way for me.

But i try it and it 's not work.

I try to figure how, but i dont know. I think is the

$HTTP_POST_VARS['lang']

he dosn't returne the value ( fr or en)

Thank you! but if you have any other idea please tell me.

Any variable in the URL is GET, not POST.

Change every occurence of $HTTP_POST_VARS to $HTTP_GET_VARS
