Can someone please tell me why this piece of code is generating a "headers already sent by.." error? This is at the very top of my PHP file, with no whitespace above it.

<?php session_start(); 
if ($pageID == 4) {
   if ($_SESSION[bcalp_docs] != "XXXXXX") {
   header("login.php");
   die();
}
} ?>

Go over this page entirely http://stackoverflow.com/questions/8028957/how-to-fix-headers-already-sent-error-in-php - it's not only "no whitespace" that will cause this. – Funk Forty Niner Jan 30 '17 at 15:36
we also have no idea where `$pageID` is defined. – Funk Forty Niner Jan 30 '17 at 15:36
If you comment out your `header()` call, you might see a "notice" on the page (which could be the cause of the headers already being sent). – M. Eriksson Jan 30 '17 at 15:39

Figured out the issue. I was missing "Location:" in my header call. – user1110562 Jan 30 '17 at 15:49
