Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter - Headers Already Sent (output Started At

I found a wonderful Captcha script and it works wonderfully, except when i use include to put it into another file...
I get this error message:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/user/public_html/index.php:12) in /home/user/public_html/securimage.php on line 386
After some short research here it appears that this happens because there is already HTML output in the main page..

I am using the include function to add it (the form) to the regular index.php page.... Do I need to add something in the headers to prevent this? Code:

Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter - Headers Already Sent (output Started At /home/user/public_html/index.php:8) In /home/user/public_html/nmdeluxe/index.php On Line 2

I'm having a problem with one of my files. I keep on getting the following error:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/user/public_html/index.php:8) in /home/user/public_html/nmdeluxe/index.php on line 2

The second line of the nmdeluxe/index.php file has the session_start(); code. There aren't any spaces before the <?php line. The file is in ANSI form. I'm also including this file in one of my other files using PHP includes.

<? include("/home/user/public_html/nmdeluxe/index.php") ?>

The public_html/index.php has that code in it. The nmdeluxe/index.php does include itself into the public_html/index.php file, but I that error message appears at the top of the page. How can I fix this?

Error -Cannot Send Session Cookie - Headers Already Sent By (output Started At Somefile:someline)

I'm new to PHP sessions and I've come across the following error:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at somefile:someline).

As well as this one:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent by (output started at somefile:someline).

The session_start(); is the very first thing in all of my code. I'm not sure what the problem is. It gave me line numbers but all I do on those lines is start the session.

Also - I have a portion of code whose POST action is another PHP page. How can I set a $_SESSION variable pertaining to this page within that action page?

I don't have an .htaccess file, so it can't be something in there. The only other thing I can think of is some kind of configuration error, BUT sessions work on other scripts... To give a little background, this script, has an inner frame, and the script in the inner frame, has a session start in it (this has all been taken out now).

Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter?

I am new to PHP, but yet I have decided to try and tackle a huge obstacle. To learn and to program PHP. Anyways I have been using an example in my PHP book, and to modify it in my own terms. Anyways I have a problem, and not exactly sure how to proceed from here. I've read that session_start(); must go before all html code and must have no white space. I believe this is true for my site but not sure. Maybe a second pair of eyes and more knowledge could help me understand why I am getting this warning. Here's my Warning- Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/YourSite/public_html/news.php:9) in /home/YourSite/public_html/header.php on line 3

Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter - Session_destory();

I'm getting this error: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent ... output started at blah blah blah.... on line 1.

Line one is <?php session_start();

This page is a login and logout page. I use session_destory(); to log the user out when a link is clicked. It redirects them to this page, with a ?action=logout in the url. I use $_GET to test if action == logout, and if it does, it calls session_destory(); and then uses javascript to redirect the user after 5 seconds to the homepage.

what does the error mean, I've seen it before, but for some reason it's not comming to me.

Warning: Session_start() [function.session-start]: Cannot Send Session Cache Limiter - Headers

I'm just starting to use PHP Sessions. I have a simple test case to see how Sessions behave which was derived using an example from a reference text. I have two scripts (Code samples below), TESTD.php and TESTE.php, each of which has a link pointing to the other. I use start sessionstart () in each of them. Using the links, I can toggle back and forth and the Session ID remains the same and a test variable which counts the toggles keeps the correct count as I toggle back and forth. PROBLEM: When script TESTE.php runs, I gets a Warning Signal (Sample below) that I don't understand. I need to understand what I'm doing wrong that is causing the warning signal and how to eliminate it. Samples are attached as follows. In attached file PHPFreakshelp-02.txt

1. TESTD.php CODE
2. TESTE.php CODE
3. TESTD display
4. TESTE display which includes the Warning

The Warning is as follows... Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/unitcons/public_html/unitresearch02/TESTE.php:2) in
/home/unitcons/public_html/unitresearch02/TESTE.php on line 9
