Re: [PHP-DB] Headers sent error msg on one server but not the other.... .

[Patel, Aman]

Check that there is no output generated before your script hits the 
Header() function calls. The most common mistake I've noticed is that if 
you require() or include() many files before you call Header(), and if 
there is any content outside of the "<?php ?>" tags in the includ()'ed 
or require()'d files (eg. a carraige return at the end, or a space after 
the "?>".

Check for that and that should fix your problem.

Hey Folks,
I have a script that times out the session if there is no activity in a 
certain amount of time.  If there is no activity the HEADER()  redirects 
to the logout page and kills the session.  Everything works fine on our 
test server, but when I test the script on the production server, I get  
an error "HEADERS ALREADY SENT..." after no activity.  I know all this 
stuff needs to be on top, before any  XHTML.

The test server has reg globals = OFF and the production server has them 
set to ON.  I can't change the any PHP.INI settings on the production 
server. Both servers are running PHP 4.3.10.  Other than that PHP 
installation is close to identical.   Any ideas / thoughts on what's 
causing the production server to send this error out?  Something to 
steer me in the right direction... I'm attaching a code snippet to look at:

           if (mysql_num_rows($result) > 0) {
            $_SESSION["valid_user"] = $email;
            }
            elseif ($t_timestamp < $c_timestamp) {
                        HEADER("Location: logout.php");
                        exit;
                 }
Best,
CH
