[PHP] Sessions in PHP... where to start???
Hi everybody! I have a problem and I was told to check out the sessions part in PHP. What I want to deal with is the following : I have a PHP page with a form, where the user writes some data. These data are then written into a file which is then used in a system command as input for an external program (NOTE: The data MUST be written into a file, it cannot be done elsewhise, because the external program takes a file as input). The thing is that I must somehow create a file everytime a user enters data into the form, so I must learn something on sessions I think. My question is, since I don't have a login system or something like that, but just want to create a different file each time (with the session_id being part of it, so that the file is unique), which session commands do I need? - Yahoo!

If it were me I'd use tempnam() to create a unique file for that particular user and then use sessions to store the name of that file in the user's cookies... http://us2.php.net/tempnam http://us2.php.net/manual/en/ref.session.php -philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well for the latter part of your question.. 'Where to start??' the first thing to start with is to NOT reply to a topic and change your subject to ask something else, instead click the icon in your email application that indicates a new message and compose your question addressed to php-general@lists.php.net Curt. -- cat .signature: No such file or directory -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Sessions and PHP
Let me rephrase it, i got a login page, once logged in you you got the session $_SESSION['in'] = true; i want to be able to count the number of people that are logged in atm, so when they logout with either logout button or close the window, i want to then decrese the number. In asp, you just used Session_Destroy() to determine if all sessions were destroyed and then APPLICATION['num'] = APPLICATION['num'] - 1 Is there anyway in php to do this? regards patrick - Original Message - From: Patrik Fomin [EMAIL PROTECTED] Newsgroups: php.general To: [EMAIL PROTECTED] Sent: Thursday, March 25, 2004 2:05 AM Subject: Sessions and PHP Hi,, is there anyway to get the number of people connected to the site? in asp you just use Application and session_terminate to accomplish this is there anyway to do this in PHP ? regards patrick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, as PHP does not have application variables. Keep a count in a file and increment / decrement manually. -- ---John Holmes...

Taken literally, you are asking about the number of active connections, meaning people who happen to be in the middle of sending or receiving an HTTP message. I think you mean something else, which is how many people have visited your site recently. You just have to determine what you consider to be recently, and then count the number of active sessions whose last visit is within that threshhold. Hope that helps.

Re: [PHP] sessions and php
Assuming PHP = 4.1
page1.php
?
// continue or create a session
session_start();
// set some session vars
$_SESSION['color'] = 'red';
$_SESSION['name'] = 'Justin';
?
page2.php
?
// continue or create a session
session_start();
// echo some session vars
echo Hello {$_SESSION['name']}, your favourite color is
{$_SESSION['color']};
// clear some session vars
unset($_SESSION['name']);
// modify some session vars
$_SESSION['color'] = 'blue';
?
Similar tests can all be found on http://au.php.net/session
