connect to db - silly variable issue

[thedefunct]

The following code is held in an appropriately named .php file.. its include()'d when db access is needed, Connect2DB is then called.. No Problem right? Well...

I receive..

Warning: Undefined variable: dbHost in path_here/dbfile.php on line number

for EVERY variable below.

What silly thing have a done wrong this time?

code follows:

<?php
$dbName = "pwd";
$dbHost = "localhost";
$dbUsr = "usr";
$dbPwd = "pwd";

function Connect2DB() {
if (ServerOpen($linkdb, $dbHost, $dbUsr, $dbPwd) == false) {
print('ServerOpen failed<br>');
die;
}
elseif (DatabaseOpen($linkdb, $dbName) == false) {
print('DatabaseOpen failed<br>');
die;
}
}
?>

Global variables are not visible inside a function unless you explicitly make them visible (check the manual section regarding the "global" reserved word). Or just move the assignments inside the Connect2DB function.

Variable scope problem - create reference to the global variables by using "global {variable}" within function.
