Cannot modify header information - headers already sent by

**MABON** · 02-12-2009

I have a

[phpBB Debug] PHP Notice: in file /includes/session.php on line 885: Cannot modify header information - headers already sent by (output started at /site/index.php:5)

on www.mydomain.com

Here are the top of the page:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<head>
<?php define('IN_PHPBB', true);
$phpbb_root_path = './../';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);
$user->session_begin();
$auth->acl($user->data);
$user->setup('');
?>

What to do?

The error you reported that you can access the http headers (as heard in the management of the session) because you've already started writing a response to the client.

it mean that your

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<head>

can not be before your session_begin. you must put it after:

PHP Code:


    <?php define('IN_PHPBB', true);

    $phpbb_root_path = './../';

    $phpEx = substr(strrchr(__FILE__, '.'), 1);

    include($phpbb_root_path . 'common.' . $phpEx);

    $user->session_begin();

    $auth->acl($user->data);

    $user->setup('');

    ?>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">

    <head>

When I put my

PHP Code:


<?php define('IN_PHPBB', true);

$phpbb_root_path = './../';

$phpEx = substr(strrchr(__FILE__, '.'), 1);

include($phpbb_root_path . 'common.' . $phpEx);

$user->session_begin();

$auth->acl($user->data);

$user->setup('');

?>

before the head, the code disappears.

What code? You mean the source code of your page? It's just the principle of a server language. If appeared, it becomes a client language.

What I mean is that when I put the code previously mentioned before:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<head>

and I save the file with the page editor, php code defined disappears.
