Thanks for your quick reply. You are right: globals are evil, at least
most of the time. I reworked the code, which now looks like:

// =====Begin sample code=====

function dbConnect()
{
$conn = mysql_connect(constant("dbHost"),
constant("dbUser"),
constant("dbPassword"))
or die("DB connection error: " . mysql_error());
mysql_select_db('blog')
or die("Error selecting blog database: " . mysql_error());
return $conn;
}

function dbDisconnect($conn)
{
mysql_close($conn);
}

$blog["dbconn"] = dbConnect();
..
..
..
dbDisconnect($blog["dbconn"]);

// =====End sample code=====

I guess it has improved a bit, hasn't it?

Cheers!
