Re: [PHP] Session and header() errrors
You can't send any output before the session_start() call. You require a file which outputs html before calling session_start(). Simply do the session_start() before the require and it should work. -Rasmus On Thu, 4 Oct 2001, Web user wrote: Why do the errors occur while running the scripts below?

Re: [PHP] Session and header() errrors
You should change sessions configuration in php.ini
The default value for sessions dir /tmp.
In windows shoud point to c:\tmp
The header error occurs because you get a warning about session.

Re: [PHP] Session and header() errrors
There are 2 things you are doing here:
1) Session start
2) page redirection
put session_start() as the 1st line in your script.
Echo commands in the included file causes such warnings:
"Warning: Cannot send session cookie - headers already sent by (output
started at c:\program files\apache group\apache\htdocs\web1\html-head.inc:9)"
The first two warnings are on account of the above problem.
The 3rd warning is becoz of the php.ini that Dimitris talks about.
For the last warning, another simple mistake:
---echo "session_id: ".session_id()."br";--
comment this line and then redirect the page.
the header() function will cause errors if you have already written, sent output
('echoed', etc) to
the current page.
