That registers a session variable. In order to access the variable
within a function without explicitly defining it as global in the
function, you need to make use of the PHP-defined $GLOBALS array.
$GLOBALS is an associative array with the name of the global variable
being the key and the contents of that variable being the value of
the array element (as per Ch. 6 of the PHP3 docs).

So, following the example code snippet from Daniel above:

$s = ("a","b","c");

function foo() {
    $localvar = $GLOBALS["s"];
    for ($i = 0; $i < count($localvar); $i++)
        echo $localvar[i] . "\n";
    $GLOBALS["s"] = ("d","e","f");
}
