Re: Sessions with mulitple pages

That's the beauty of sessions. The customers browser keeps track of the session for you.(sort-of)
All you have to do is put session_start on each page and then use your variables. Each customer(browser) will have their own session and variables.

To see this in action, just create some sample session pages. Use session_id() to print out the id #'s.
Now, open the page up in two different browsers on your machine. Both have different session id's, but the id stays the same until you close the browser(or it times out)

Problem with the time elapse example

Well, not sure if it's a problem, or I just don't understand.

My question/problem: When refreshing the browser, it resets the session. I get a new session id and the script doesn't ever tell the time.
I put a link on the page to itself, click on that, and it works as intended(doesn't reset the session)
Is this how it's supposed to work? Or is there some setting in the configuration that changes how this works?
thx
Brian

Re: cookie

Which might be said plainer, too.

If you have initialized a session using 'session_start()' you also can use 'session_id()'.::

<?php
// start the session
session_start();
echo "<a href=\"nextpage.php?PHPSESSID=" . session_id() . "\">Click for next page</a>";
?>

There is an important security breach to consider: even if you carefully do not add the session id to external links, the session id will be visible in the referer.

Re: cookie

Okay, sorry, that sucked. The "structured text" is obviously *not* implemented completely here...

The example from above which was gorked was (replace [] with < or >):

[?php

// open session

session_start();

// create GET session id variable

$mysessionid = "PHPSESSID=" . session_id();

// give an example of use

echo "[a href=\"nextpage.php?" . $mysessionid . "\"]Click for next page[/a]"

?]
