How sessons work?

[deep]

Hello,

I was wondering, how do sessions work? Does the information stored in a session get stored on the clients computer or is it something that will take up space om my server?

Thanks.

it is
a small 'session file' with values of $_SESSION variables
that is stored in C:/temp/
windows temporary files folder

One such file for every client, browser that is connected to your server
this file's contents is deleted, when client closes down browser = session over
file can still be there, but size is 0 bytes = empty

When client opens browser again and connects, a new temp file is created
with a new session id number = filename

you can specify in php.ini
if you want to use another Custom folder for storing php session temp files

To see what your server uses, run phpinfo();

<?php
// save this as 'phpinfo.php' or 'phptest.php' or 'test.php'
// and run it, to get info about your server php.ini settings and more
// also tells info about settings use for SESSIONS, like 'session temp save path'

phpinfo();

?>
