SSIncludes in PHP

I am using $_SESSION["usrname"]=$_POST["username"] construct to set $_SESSION variables. My question re Apache is that the SSI variables are not getting displayed in php scripts and the $_SESSION data is not appearing in shtml. The $_SESSION data works fine in php scripts and the server side includes(SSI) works fine in shtml.....:-( What have I forgotten to do to get both php and shtml to work the way I want? -- Regards, Alf Stockton www.stockton.co.za You are scrupulously honest, frank, and straightforward.
