Headers Already Sent?

Hi guys,

When I try to run the following code

I get these three errors:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/content/42/9125042/html/user.php:1) in /home/content/42/9125042/html/user.php on line 1

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/42/9125042/html/user.php:1) in /home/content/42/9125042/html/user.php on line1

Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in /home/content/42/9125042/html/user.php on line 4
Why?
I thought if the first thing I did was start the session, without any output on the page, headers weren't sent yet.
What might be sending the headers?

Thanks,

Hi there, did you include a file on the first line? if not you have a BOM problem

Well, the first line was <?, and then the session stuff caused an error.
I'll check that link in the morning... yawn.

Then BOM (unreadable start of your document) is causing the problem. Gl.

 

Try to put ob_start on first line of page http://php.net/manual/en/function.ob-start.php

 

When the script starts with session_start and gives an error that would not solve the problem don't you think?

 

I told my editor (Notepad++) to convert the file to 'UTF-8 without BOM'

It doesn't come up with the error anymore!

Thanks,
