[Tomm]

Sorted:

<?php
$logoutGoTo = "link/to/your/page/you/want/after/logout.php";
session_start();
unset($_SESSION['username session name here']);
unset($_SESSION['group name session here - delete if not needed']);
if ($logoutGoTo != "") {header("Location: $logoutGoTo");
session_unregister('user name session name here');
session_unregister('group name session here - delete if not needed');

exit;
}
?>

put in .php file and link to it

Thats for logout let me think for protected pages

Ok protected pages:

<?php
session_start();
$authorizedUsers = "";
$donotCheckaccess = "true";

// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) { 
  // For security, start by assuming the visitor is NOT authorized. 
  $isValid = False; 

  // When a visitor has logged into this site, the Session variable Username set equal to their username. 
  // Therefore, we know that a user is NOT logged in if that Session variable is blank. 
  if (!empty($UserName)) { 
    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login. 
    // Parse the strings into arrays. 
    $arrUsers = Explode(",", $strUsers); 
    $arrGroups = Explode(",", $strGroups); 
    if (in_array($UserName, $arrUsers)) { 
      $isValid = true; 
    } 
    // Or, you may restrict access to only certain users based on their username. 
    if (in_array($UserGroup, $arrGroups)) { 
      $isValid = true; 
    } 
    if (($strUsers == "") && true) { 
      $isValid = true; 
    } 
  } 
  return $isValid; 
}

restrictGoTo = "access/denied/page/here.php";
if (!((isset($_SESSION['Username'])) && (isAuthorized("",$authorizedUsers, $_SESSION['username session name here'], $_SESSION['usergroup name session here - delete if not needed'])))) {   
  $qsChar = "?";
  $referrer = $_SERVER['PHP_SELF'];
  if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
  if (isset($QUERY_STRING) && strlen($QUERY_STRING) > 0) 
  $referrer .= "?" . $QUERY_STRING;
  $restrictGoTo = $restrictGoTo. $qsChar . "accesscheck=" . urlencode($referrer);
  header("Location: ". $restrictGoTo); 
  exit;
}
?>

[Tomm]

you put it in the body tags! lol

Put this before ANY CODE:

<?php
// set your infomation.
$dbhost='localhost';
$dbusername='extreme_*****';
$dbuserpass='*****';
$dbname='extreme_*****';
session_start();

// connect to the mysql database server.
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die('Cannot select database');
?>
