Errors With PHP Session

Question

Just wondering if there are any alternative ways to use session_start() and also having my header.php in every page without getting the below warning? Help?

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

Here's the code.

<?php
session_start();
?>
<? include('header.php'); ?>

So mark one of the answers, which worked, as the solution. :) — Jim, Jan 26 '11 at 18:29

You should be calling session_start() before any output. Why can you not move the two around?

Make sure nothing is output when you run session_start(), it should be run once at the very start of your web page being requested.

This issue doesn't need resolving via JavaScript, you just need to restructure your code.

Yes, you have to use session_start() before outputing anything.

If you use session_start() before including you header.php, this should work.

you don't have to - http://php.net/ob_start – Kamil Tomšík Jan 26 '11 at 18:31
ob_start, used for this purpose, would be just a workaround – Arnaud Le Blanc Jan 26 '11 at 18:41

Start your session before you include header.php
