That doesn't seem entirely right-- global $var1, $var2; should still 
work just fine. What's been turned off is probably "register_globals" 
which only applies to server environment and CGI request variables, not 
variables that you declare at runtime.

file:///usr/local/share/doc/php/configuration.directives.html#ini.register-globals

If either $var1 or $var2 are really $_GET['var1'] or $_GET['var2], then 
you'll need to explicitly assign them in global scope like so:

<?php

function foo() {
    global $var1, $var2;
    return $var2.$var1;
    }

$var1= $_GET['var1'];
$var2= $_SERVER['DOCUMENT_ROOT'];

?>

Should work...
