<?php

header("Location: login.php");
}//if
include("masterHeader.php");
$location = "Physician Education";
?>
Here is the error I am getting
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at \\intellicom05\Company\Customers\ColglazierClinic\Web\www\doctorArea\docwork.php:1) in \\intellicom05\Company\Customers\ColglazierClinic\Web\www\doctorArea\docwork.php on line 2

I have worked with sessions and headers for a long time, but I can't seem to see what I'm missing here. Thanks,

1. You have a space or some other character in front of your <?php tag on the page. Check your page in several text editors (Notepad++, ConTEXT, regular notepad, etc.) to make sure that your current one isn't inserting something before the <?php tags for some reason.
2. Your server is, for some reason, configured to send headers before executing the PHP code. I'm not an expert on this, but if this is the case it's almost certainly an Apache or IIS configuration problem.
I ran into a very similar problem. Code seemed 100% legit. But I got errors trying to view the page. Copy-and-paste the code to a new page; voila! Page works! But the original page (with same code) did not! Exceedingly frustrating!
After hours of debugging... I noticed (in Notepad++) that my "error" page was in MAC format, while the rest of my pages were set in UNIX format (my preference). Turns out (as WesleyC indicates), my page being in MAC, on a UNIX machine, somehow managed to cause an invalid character or such that threw PHP off. I resaved the file in UNIX format (same code); problem gone.
Hopefully your issue is as simple!
