Automatically appending a variable

[Anon]

Is the a way to set up php so that a variable is automatically added to every php page that is opened?

For instance, I would like whatever.php, when called to open as whatever.php?lang=en

and this variable to always be appended to every php page no matter what I did. - browsing pages, followinf links, submitting forms etc.

Can this be done?

One thing you could do is an include file that sets up suitable session variables, then fiddle with your php.ini's auto_prepend_file setting.

<?
session_start();
session_register('lang');
if($lang=='' || !isset($lang)){$lang='en';}
?>

Of course, if $lang is read only and doesn't change throughout the site (hardly deserving the name 'variable') then the sessioning and setting the default value is unnecessary, and the include file could then be

<?
$lang='en';
?>

Rather then the variable just appearing in the script I need it to actually appear in the address bar. This is so the logging on our website will be able to differentiate between different territories. I want this variable to appear automatically, so I don't need to go through every single script and make sure that when another page is opened, the country/language variable is carried across.
