Re: [PHP] some questions on sessions (long)...
How about the sessions? doesn't sessions also needs to send header data (before any other output)? the sessions are registered normally..

But what about the session? It get's registered... doesn't sessions also need to send header information? it gets registered... it just doesn't persist...

Re: [PHP] some questions on sessions (long)...
Your problem probably is including the miec.php from the .shtml document. Does the .shtml document send any output to the browser before including your .php script? If so, you're not going to be able to send any cookies from the .php script. Once any standard output makes it to the browser (including any leading whitespace), no more headers can be sent to the browser. PHP sends cookies to the browser as header data. Hence, if your .shtml document has any output before your .php document is included, your session cookie cannot be sent. ~Chris /"\ \ / September 11, 2001 X We Are All New Yorkers / \ rm -rf /bin/laden On Mon, 12 Nov 2001, Christian Dechery wrote: > I've recently had a problem with sessions, and came up with a problem that > apparently has no solution... > > I want to understand why EXACTLY it does't work... > > From what I understand about sessions (reading PHP Docs), cookies are > default and URLs holding the session_id are used if the cookies can be used > to get the current session_id right? > > So if, there's a cookie indicating a session, PHP will detect it and the > session will work beatifully.. > If when a session is created, a cookie cannot be set, then the URLs come > into play.. right? > > -- I'm I right so far? -- > > So, I can only presume, that whenever I can see those URLs with > session_ids, this means that no cookie was created... and if one of those > URLs is clicked, the session will persist, since the URL is carrying the > session_id. > > Well, now to the problem with no solution...
