Pear and Session Header Problem - El Forum - 05-27-2008

Hey there,
This has really stumped me, mainly because its a little out of my area of knowledge with code igniter (and headers). I have integrated PEAR with CI (following the wiki guide) and for some reason I get this error message on all my pages:
A PHP Error was encountered
Code:
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /(path to CI)/system/application/hooks/pear_hook.php:15)
Filename: libraries/Db_session.php
Line Number: 248I am familiar with the role of headers, but what I can't understand is why Db_session is trying to send headers here - I don't call it anywhere on the site, and use Freak Auth. I also have the Zend Framework installed. Funny thing is, they were all integrated with guides from 4webby, so that leads me to believe it is a problem with my stuff.
Is there anything I could be doing in my code that would be conflicting with PEAR in this way or causing a problem with the Db_session library? Here is the section of code that line 248 hangs out in:
Code:
/**
* Write the session cookie
*
* @access public
* @param boolean true if we want to send cookie even if a cookie has already been sent
* @return void
*/
function sess_send_cookie($force = FALSE)
{
if ( !$force && $this->cookie_sent ) return;
log_message('debug','sending session cookie');
setcookie(
$this->sess_cookie,
$this->userdata['session_id'],
$this->sess_length + $this->now,
$this->object->config->item('cookie_path'),
$this->object->config->item('cookie_domain'),
0
);
$this->cookie_sent = TRUE;
}
// END sess_send_cookie()Any guidance would be greatly appreciated!

Note to self: take a long deep break and THINK before posting to Code Igniter forum.
I remembered that header problems can often times be caused by spaces after the ?> php tag. Sure enough, the PEAR hook had a space and that was tripping it up.
Hopefully this is somewhat useful to someone who runs into the same problem...
...right...

Wow, just saved me a headache by looking at two posts. It really is the space after the ?> that was preventing mine from working. I was always wondering why the 'redirect' function never worked, now I know. This helped tremendously!
