Headers already sent by PHP
i know this is a very common problem and I have googled alot for this but still no success. I am getting this error
Warning: Cannot modify header information - headers already sent by (output started at G:\xampp\htdocs\bidding_site\inc\header.php:88) in G:\xampp\htdocs\bidding_site\inc\add_project.php on line 8
I have checked that there is no white space before the header(). below is my code of add_project.php
<?php
if(isset($_SESSION['user'])) {
echo "hello world";
}
else {
header('location:../index.php');
}
?>
The error message has already explained what has happened; inc\header.php sent some output (e.g. with echo, print or by something outside the PHP tags) on line 88.
That said, this is an extremely common problem, there are other answers here on SO and googling shows plenty of answers, so this should be closed.

I keep having some trouble with a bit of coding. I've tried everything to fix it. All the tips on this forum, everything. I was wondering if someone could lend me a hand.
I'll leave you the offending piece of coding here to see if anyone might want to take a crack at it.
}
fwrite($handle, "\r\n");
fwrite($handle,"\t\t\t\t\t\t
==============================
========================");
fclose($handle);
echo "Invalid E-mail/Password <br>";
echo "Try Again";
header("Redirect:2;url=index.html");
?>
I'm new at coding as you can probably guess so any help would be much appreciated.
2 Point Based Comment in PHP Manual:
Remember that header() must be called before any actual output is
sent, either by normal HTML tags, blank lines in a file, or from PHP.
PHP Manual
<?php
header("refresh:2;url=index.html");
echo "Moved in 2 second";

I am facing a problems with my wordpress site and i cannot see anything on my login screen : http://vtrails.us/login - It's blank.
But in my error_log file i am looking a problem
PHP Warning: Cannot modify header information - headers already sent by (output started at /home/vtrailsu/public_html/wp-content/plugins/mix-tape/update_calls.php:198) in /home/vtrailsu/public_html/wp-includes/pluggable.php on line 1228
But I cannot see anything on update_calls : line 198 (see above)
So what can be it's solution? Can i get more information about it?
Don't use ?> at the end of php script. Closing tag is optional. + there are 2 newline characters after ?> which make output.
Use ?> closing tag only when you want to write pure html after that

Error is:
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/gopal/public_html/Update.php:1) in /home/gopal/public_html/Update.php on line 2
Quick hack? Use Output control.
However, what you really should be looking for is any kind of content that has been rendered before session_start has been called. This method should be the second line of code in your application:
<?php
session_start();
/* rest of site */
"headers already sent" this means that a script outputs to browser something (a space, a character or a BOM element)
make sure your includes files do not echo anything.
If that is verified and you still get the message, then i guess it's a BOM element (usually in utf-8 encoded documents/pages)

The Insert works perfectly as tested that without the header redirect.
My problem is i'm using MYSQLI with Object oriented approach and still new to it. When i have the header redirect in there it tells me in the browser
"Warning: Cannot modify header information - headers already sent by
(output started at /home/hawkwsco/public_html/admin/include/template/doc.inc.php:1)
in /home/hawkwsco/public_html/admin/include/library/functions/process/process.inc.php on line 10"
My code is below:
<?php
require ($_SERVER['DOCUMENT_ROOT'].'/admin/include/config/config.inc.php');
$query = ("INSERT INTO page(pa_id, pa_page, pa_page_info) VALUES ('NULL', '{$_POST['page']}', '{$_POST['info']}')");
$mysqli->query($query);
header("Location: http://".$_SERVER['SERVER_NAME']."/admin/content.php");
exit;
?>
What am I doing wrong?
Most likely the file you are including has some text in it being output (even a newline at the end of the file is enough) causing the output to start before the header can be sent. I usually make sure my includes do not have a ?> at the end to avoid this problem.
Alternatively, you can use output buffering (ob_start()) to avoid any output being sent until you are ready. ob_start() must be called before any output to be effective.

When i use header( 'Location: index.php) in php code it display this error message.
Warning: Cannot modify header information - headers already sent by (output started at D:\xampp\htdocs\OnlineCode\online\survey\code\index.php:55) in D:\xampp\htdocs\OnlineCode\online\survey\code\index.php on line 62
how can i fixed this ?
make sure there is no echo or print statement before redirecting the header.It cause this error when we use echo or print before redirecting the header.
This occurs when output has already been started. You have to put the header() calls before any output occurs. Even spaces outside of php tags count as output. It may be helpful to just post the page's code where we can look at it.
