determining language of user

Recommended Posts

I would like to know if this code works. I am trying to determine the language the user is using, but I don't know of a way to check this. For example, if a user is using French, will the variable $lang receive the value of 'fr'? Thanks in advance.

<?php

// session_start();
error_reporting(E_ALL);// can be removed later
if (isset($_GET['lang'])) {
$lang = $_GET['lang'];
$_SESSION['Language'] = $lang;
} else {
if (isset($_SESSION['Language'])) {
$lang = $_SESSION['Language'];
}
}
if (!isset($lang)) {
switch (substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2)) {
case 'fr': $lang = 'fr'; break;
case 'de': $lang = 'de'; break;
case 'ko': $lang = 'ko'; break;
case 'es': $lang = 'es'; break;
case 'it': $lang = 'it'; break;
case 'ja': $lang = 'ja'; break;
case 'pt': $lang = 'pt'; break;
case 'zh-CN': $lang = 'zh-CN'; break;
default: $lang = 'en';
}
}
echo $lang;
?>

According to the manual, $_SERVER['HTTP_ACCEPT_LANGUAGE'] is not one of the predefined variables available.

Refer to [a href=\"http://us2.php.net/manual/en/reserved.variables.php#reserved.variables.server\" target=\"_blank\"]http://us2.php.net/manual/en/reserved.vari...ariables.server[/a] to see which variables are available by default.

I did refer to that manual beforehand, and used it to put together this code. Also, look at
[a href=\"http://www.developershome.com/wap/detection/detection.asp?page=readHeader\" target=\"_blank\"]http://www.developershome.com/wap/detectio...page=readHeader[/a]
and scroll down to header "Retrieving HTTP Headers with PHP" and you will see it listed as OK.

Fair enough...I never actually looked at all the elements in the server array before. On my home server, the value of that particular element is:

[HTTP_ACCEPT_LANGUAGE] => en-us,en;q=0.5

So, I don't see any reason, off hand, why your code wouldn't work.

Well, if you comment out session_start() then there is no session to use $_SESSION.

Let me ask the question differently:

Is there someone who has English as a secondary language installed on their machine, and with one of the other listed languages as their primary.

If yes, can you copy and paste the code into a .php file, run it, and let me know if your default language is indicated or is "en" indicated.

thanks.

Yes, you are correct, session-start should be uncommented. thanks.
