can I still send cookies after I've called session_start()

[lkrubner@geocities.com]

I was trying to set a cookie before I called session_start() and it was
giving me an error. But isn't sessions really just a cookie? Why would
it matter if I sent a cookie before session_start? Can I set them
afterwards?

Re: can I still send cookies after I've called session_start()

You *can* set a cookie without calling session_start() . Do you mean a
session variable? You can't do this without calling session_start() :
$_SESSION['sessionvar'] = 'value';
But you can do this:
setcookie('cook iename', 'value', time()+36000);
and then read the cookie like this:
$_COOKIE['cookiename'];

No, I meant, I was setting a cookie, then calling session_start() , and
I was getting an error. Can I call session_start() and then set a
cookie? I want to set a permanent cookie that will last one million
seconds. I also want sessions.

Your post is missing a vital piece of information.

Yes, and before.

This is the error I'm getting:

<b>Warning</b>: session_start() : Cannot send session cookie - headers
already sent in
<b>/home/httpd/vhosts/publicdomainsof tware.org/httpdocs/pdsIncludes/CommandStartSes sion.php</b>
on line <b>14</b><br />
<br />
<b>Warning</b>: session_start() : Cannot send session cache limiter -
headers already sent in
<b>/home/httpd/vhosts/publicdomainsof tware.org/httpdocs/pdsIncludes/CommandStartSes sion.php</b>
on line <b>14</b><br />


This is line 14 and 15 of CommandStartSes sion:

session_start() ;
session_registe r();


I used my text editor (RedCrimson) and did a search of all the files in
this project, looking for session_start() . I thought maybe, by
accident, I was calling it twice. But no, it only appears once.

Oddly, when I call session_start() , output buffering is on, so I'm not
sure how I get that error. Later I set a cookie, then I sent a charset
header indicating that the characters are UTF-8, then I end output
buffering.

I thought the output buffering would keep me safe from this kind of
error, but apparently not.

<b>Warning</b>: session_start() : Cannot send session cookie - headers already
sent in

You're sending <br /> before the session_start call.

You can't send ANYTHING (including a blank line) before the session_start() call.

That's part of the PHP error message:

andyh@server:/usr/src/php-5.0.4/main$ nl -ba main.c | grep -2 '<br />'
736 char *append_string =
INI_STR("error_ append_string") ;
737 char *error_format = PG(html_errors) ?
738 "%s<br />\n<b>%s</b>: %s in
<b>%s</b> on line <b>%d</b><br />\n%s"
739 : "%s\n%s: %s in %s on line
%d\n%s";
740 php_printf(erro r_format,
STR_PRINT(prepe nd_string), error_type_str, buffer, error_filename,
error_lineno, STR_PRINT(appen d_string));
