Global variables

[Alf Stockton <alf@xxxxxxxxxxxxxx>]

The following scenario has me confused. In my main program I have:-
<?php
$link = '';
.....snip......
?>
in an included function I have
<?php
function PMConnect() {
    global $dbservertype, $servername, $dbusername, $dbpassword, 
$dbname, $link;

    $link = mssql_connect("$servername", "$dbusername", "$dbpassword");
    if (!$link) {
        sprintf($Message, "At %d in %s Could not connect to %s at %s as 
%s",__LINE__, __FILE__, $dbname, $servername, $dbusername);
        trigger_error(E_USER_ERROR, $Message);
        }
    if (!(mssql_select_db("$dbname", $link))) {
        sprintf($Message, "At %d in %s Could not select %s at %s as 
%s",__LINE__, __FILE__, $dbname, $servername, $dbusername);
        trigger_error(E_USER_ERROR, $Message);
        }
    echo "In PMConnect() link = $link<br>";
    }
?>
and here the echo shows that $link contains data but now in another 
included function I have
<?php
function GetActive($Datum) {
    global $link;
    echo "In GetActive() link = $link<br>";
.....snip......

this echo shows that $link is empty.

NB. All my functions are contained within .inc files that are 
incorporated via something similar to include('includes/PMConnect.inc');
What am I misunderstanding ?
