How to fix "Headers already sent" error in PHP

Closed 1 year ago.
I have some issues in my application, I uploaded it to a domain server and have this ERROR here:
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/emavula/public_html/deco.co.mz/store/login_admin.php:1) in /home/emavula/public_html/deco.co.mz/store/funcoes/funcoes.php on line 4
It sounds like some output was sent in /home/emavula/public_html/deco.co.mz/store/login_admin.php:1. Because it is on line 1, I strongly suspect a new line or space before <?php. If it isn't that, maybe check the error log and make sure the log level is set to at least warning.

How to fix "Headers already sent" error in PHP

After reading other similar question this is what I understand. I can set my own session_save_path() but i am on a shared host and can't set the save path above public_html. For session_start() headers alredy sent there is nothing else above my session_start() statement. The second warning says output started at 2 lines of index.php that is exactly where I have set session_start().
Here is the exact error i am getting
Warning: session_start(): open(/home/users/web/b2659/ipg.apnasikkacom/cgi-bin/tmp/sess_d48d5bfff4fc5df81ab868122feec5e3, O_RDWR) failed: No such file or directory (2) in /hermes/bosnaweb04a/b2659/ipg.apnasikkacom/8mags/bored/people/index.php on line 2

I have put session_start() at the top of my PHP file.
Here is the code
<?php
session_start();
$mysqli = new mysqli($db_hostname,$db_username,$db_password,$db_database);
and other PHP code. I am using some PHP templates like this
<?php include_once("../../templates/socialtemplate.php")?>
but all these includes are after the first section of session_start() code.

I dont know why I'm having this error:
Warning: session_start(): Cannot send session cache limiter - headers
already sent (output started at
/home/jogarspy/public_html/index.php:2) in
/home/jogarspy/public_html/core/init.php on line 3
In my init.php there are just one session_start();
How can I fix it?
Starting a session sends a cookie to the browser. This is in the HTTP header. Therefore do it before sending any other output as this will tell the web server the headers are good to go.
session_start() needs to be on the very first line of the file.
Look at "Starting a PHP Session"

My site is running fine on one server but when I shifted it to another server, some pages are giving following warning message.
Warning: Cannot modify header information - headers already sent by (output started at /home/parviz/public_html/ganj_videos/lang/english.php:1) in /home/parviz/public_html/ganj_videos/mobile/detect.php on line 50
Any idea on how to fix it?
Thanks.
Most likely your new server has a different setting for the errors and warnings. If PHP issues a warning or error as output then it will cause your headers to fail.
Change the level using the error_reporting function.
Just follow the debug: it says output started in file /home/parviz/public_html/ganj_videos/lang/english.php on line 1. There's most probably some messy newlines or spaces there. Make sure all php files executed start with <?php and NOTHING else before it, or you'll get the warning.

I have created a dynamic menu CMS website. I developed in a Windows system. When i run my project in windows operating system, My project runs without any error. But now uploaded it into Linux Operating system server i am getting warning & error like:
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/ansofcm8/public_html/apps/resources/math/application/core/MY_Controller.php:1)
Filename: libraries/Session.php
Line Number: 675
What could be the reason. Please help me.
There seems to be whitespace before the php open tag <?php in MY_Controller.php.
Check all PHP files and remove the whitespace before the <?php tag. If there is a space or new line, the body of the http request is started, and you can't add new headers to the http request.

If you have saved your file in UTF-8 format, be sure to check if it is UTF-8 without BOM.
Did you include this file from any other file? If so, then did those files echo/output anything?
The HTTP header that includes cookies must be outputted before the body (the HTML, usually).
Along with rFactor's response, check that you do not have any white space at the top of the PHP file (e.g. a space or a period).
Changed encoding from UTF8 to ANSI, then saved the file and the error went away.
