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

Oct 15, 2007

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

Nov 13, 2007

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)

Feb 17, 2011

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.

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

Jan 25, 2010

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

Session Expired Or Never Started?

Jul 17, 2005

I have some code at the top of each page that says session_start() then
checks for a value in the session. If the person never logged in the
session is empty and they get bounced to the login page. But if the person
has been sat at a normal page for 15 minutes after logging in,
session_start() works as if a session ID has not been presented, starts a
new session which is empty and the user gets bounced to the login page!

I feel like I've missed a step. How can I tell if a user doesn't have a
valid session ID because they've never logged in, or whether they don't
have a valid session ID because their session has timed out?

if(!isset($_COOKIE["PHPSESSID"]))
{
session_start();
}

but this time i got this warning message:

is there a better way to check if session has already started?

if i use @session_start will it make things work properly and just shut up the warnings?

Zend_Session: Session Must Be Started Before Any Output Has Been Sent To The Browser

I've run into this issue before, but I can't remember how to solve it. I have created a bare bones (can't get any simpler) controller, and am just trying to echo something to the browser, and I am getting this message:

Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'Session must be started before any output has been sent to the browser ...

Here's my entire controller. It's displaying 'success', but it also displays the error message. How can I silence that error message so I can simply echo something to the browser?

Code Ignoring Valid Session From Earlier Successful Login?

Mar 16, 2010

I have a login script that when successful, should check to see if the session exists, if not, display login form, once posted, authenticate, if successful, set session. After I successfully post the form, and it binds successfully, then go back to the page, it completely ignores the session and displays the login page. I don't know what I am doing wrong, do I have the conditionals in the wrong order? Should I be looking for the session before testing to see if the form was posted?

<?
session_start();
// using ldap bind
if(isset($_POST['username']) && isset($_POST['password'])) {
$username = $_POST['username'];
$password = $_POST['password']; // associated password

This code should hit the die() clause. However, it's not. If I try to loop through the query results it will throw an error there, but the trap will not catch it. The only thing I can think of is I have 2 connection strings in my config file that look like this: Code:
