Php 4 to 5 help please

[nohoper]

Hello to everyone! I've got a script written in php4 and would like to convert it to php5, I can't find either a paid or open source version of any script similar. I don't know enough to do this myself, but can work it all out if someone could give me a hand with this first part, how would this be written in php5?

 

<?php

session_start();

// Require standard files

include("./require/config.php");
require("./require/authmember.php");
require("./require/functions.php");

include("./include/get_config.inc.php");
$content="./include/index.inc.php";
if(session_is_registered("valid_user")) {
$menu="./include/menu_v.inc.php";
} else {
$menu="./include/menu_u.inc.php";
}

//Page Description
$page_title="Welcome to $site_name";

//Meta description tag
$description="";

//Meta keywords tag
$keywords="";

include("./include/header.inc.php");
include("./include/body.inc.php");
include("./include/footer.inc.php");
?>

 

Your help would be most appreciated, thanks in advance.

The only part to replace is

if(session_is_registered("valid_user")) {

with

if(isset($_SESSION["valid_user"])) {

Its use of session_is_registered() suggests that you'll have a lot more work to do in other places...
