Warning session start line 1

[alejandro52]

I keep having the same problem when i run my script on the server. the error is

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/alliapop/public_html/ekloges2010/ekloges2010/eisagogi.php:1) in /home/alliapop/public_html/ekloges2010/ekloges2010/includes/session.php on line 1

I know i have to put session start at he very first line and i did but the problem keeps showing up. What else should i check?

Is there anything else before the session_start()? Even a space or a line-break before the "<?php" will set this error off.

[alejandro52]

from what i see there is nothing. I tried everything, putting space and removing it pressing backspace and all.

Are you printing anything in a different file, and then starting the session? If you have something like this, that will cause this error, too:

 

index.php

<?php

echo 'Oh, hi!';

include 'sessions.php';

?>

 

sessions.php

<?php

session_start();

?>

no i don;t print anything.

Whatever is on line 1 of eisagogi.php is generating the output. If there's even so much as a line feed before the opening <?php tag, it will send it to the browser.

Did you use an editor that saves it as UTF-8 with BOM (byte order mark)?

[alejandro52]

IF i don't fix the error will there be any problems on my web page besides showing the warning?

no . will notepad work?

Your code won't work because you cannot output anything to the browser before a statement that uses a header, like a session_start(), a setcookie(), or a header() redirect.

 

If the BOM characters are the problem, you must either save the file as a UTF-8 encoded file without the BOM or you must save the file as a ANSI encoded file.

i just ran into this exact same problem yesterday, given an HTML file that I needed to add PHP to.

 

<?php as the very first item on the very first line, session_start() on the second line, but I still got the headers/session_start() warning.

 

As people are figuring out: I had to save the file as UTF-8 without BOM. The error then went away.
