Warning: session_start() [function.session-start]: Cannot send session

Advertise On This Page

Note: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

The other day i kept getting this error:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /var/www/a-header.php:10) in /var/www/header.php on line 26

so to fix it I moved the session_start() function from line 26 to line 1 on my header.php file.

That fixed it.

I am posting here just incase anyone else is getting it..

Description
bool session_start ( void )

session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.

If you want to use a named session, you must call session_name() before calling session_start().

session_start() will register internal output handler for URL rewriting when trans-sid is enabled. If a user uses ob_gzhandler or like with ob_start(), the order of output handler is important for proper output. For example, user must register ob_gzhandler before session start.

Notes
Note: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

i have faced this error at several occasions.an easy way to tackle is

place

<?php session_start(); ?>

as the top most line of the page.
try to write it in a single line itself.make it a practise and i hope you wont be in trouble in future.

utf-8 without bom fixed my session_start() errors. thanks.

to actually see the bom i opened the page in cpanel's editor in iso-8859-1, it didn't show in utf-8,.... go figure.
my page was created from a dream weaver template while edit - preferences - new document was set to utf-8 with bom. save-as utf-8 no bom only worked for first save , then ctrl s defaults back to utf-8 with bom (grumble...)
i regained control by changing edit - preferences - new document to utf-8 with no bom. then created new document from template and copied my php and html from the troublesome page(which i then joyfully deleted) to the new one.
thats the contact page done, now for the shopping cart.(cross fingers)

hostman:

if that's the case, then you need to check any of your includes, check for any blanks or white spaces on line one of any of the files, if you are getting this errors, its because you are sending some information to the browser before the sessionstart function. you just have to check and doublecheck, eventually, you will find it. it happened to me, i went crazy trying to find it, but eventually, i found it. just remember, you can't have anything before sessionstart

you can also get more help at:

http://www.php.net/manual/en/function.session-start.php

Description

bool session_start ( void )

session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.

session_start() will register internal output handler for URL rewriting when trans-sid is enabled. If a user uses ob_gzhandler or like with ob_start(), the order of output handler is important for proper output. For example, user must register ob_gzhandler before session start.

Notes

Note: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

as you can see, even the official php site says you must call session_start() before anything you send to the browser, that includes white spaces. white spaces are hard to find, because you can't see them, you have to look for them
