Disabling Browser Cache and Redirecting

[tstout2]

Hey all!  I currently use ASP for most of my pages, but I am working with an application that is in PHP.  I need some help protecting my index.php as i have been doing with my ASP files, so can someone help me translate the following ASP code in the PHP equivalent?

 

Thanks so much for any help!

 

Current ASP code:

 

<%@LANGUAGE="VBSCRIPT"%>
<% Option Explicit %>
<%    
    'This page will not be cache by the browser (security reason)!
      Response.CacheControl = "no-cache"
      Response.AddHeader "Pragma", "no-cache"
      Response.Expires = -1

    'This will make sure no user can access this page without login into the system first,
    'If the user type this page address directly into the browser, they will be redirected into the login page!

      If Session("name") = "" Then
         Response.Redirect("index.asp")
      End If
%>
