Error with sessions

sunita

i am getting the error
"Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent ".
i had checked a few messages posted with a similar query and the answer given was to check if there were any blank spaces before session_start().
I find no such spaces in my program.What else could cause this problem?
Could some please help me....
thanx

OhLordy

"Headers already sent" means that something is being outputed to the browser before the session is being used. This is not allowed.
If you are still having problems please post your code.

There are two ways to solve this problem

1) Re-write your code so that things like setcookie and header("location blah blah bla") are called before anything is sent to the browser (NOT ALWAY POSSIBLE / DESIRABLE)

2) put ob_start() at the top of your script and then ob_end_flush() at the bottom

What the 2nd one does is store everything between the two statements in a buffer. Then when the "ob_end_flush" is called all the contents of the buffer are sent to the browser.

Go take a look at this section of the php manual

Greetings.

I too am having error/warning messages in my session handling.

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

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

<?php
ob_start();
session_name('TestSession');
session_start();
$sessVar = 'Peace';
$reg  = session_register('sessVar');

if ($reg) {
	echo "Success in registering the session variable.<br>";
	echo "The session variable = ".$sessVar.'<br>';
	echo "The session variable = ".$_SESSION['sessVar'];
} else {
	echo "There was an error in registering a session.";
}
ob_end_flush();
?>

Using PHP 4.3.1 Apache 1.3.27 Linux 2.4.19

Thank you very much in advance.
