You can run an example test via browser to see it in action:
-----------------------------
$name = isset($_GET['name']) ? $_GET['name'] : 'PHPSESSID';
echo 'Name: ' . $name . '<br/>';
session_name($name);
session_start();
echo 'Cookie/Session name: ';
echo session_name();
echo '<br />';
echo "Value: " . session_id();
echo 'Name: ' . $name . '<br/>';
session_name($name);
session_start();
echo 'Cookie/Session name: ';
echo session_name();
echo '<br />';
echo "Value: " . session_id();
--------------------------
Change ?name=SESSION_Name

Your assumption is correct.When you create a session there are 2 ways it gets tracked. Via URLs or via the session Cookie. By default, it is stored in Cookies when it can.So when you do session_name('TEST'), a cookie named TEST will be created and it would have the value of the session id.On Thu, Jan 27, 2022 at 11:28 AM <paulf@xxxxxxxxxxxxxxxxx> wrote:Folks:
I've been using session_start() and session_name('something') for years
without thinking much about it. But I've started to wonder if there's
an advantage to "naming" a session versus simply allowing PHP to assign
a session ID to it. This had dredged up other questions I haven't been
able to find the answers to.
I have some finance software with various forms, and a menu to navigate
to the different pages/forms. Assuming I run session_start() at the
beginning of each page, under what circumstances would PHP actually
create a new session with a new ID?
I know there's a time limit on sessions in PHP, but is it reset for
each access?

what software I run on that server, using a specific running browser,
I'll get the same session ID, according to session_id(). That is, if
I'm connect to localhost (for example), in Firefox, I can visit any PHP
software I've written on that server in any tab and get the same
session ID. A different user will get a different session ID on their
machine/browser.

different session for each piece of software I write. (Assuming I tell
each piece of software to set a different session name when it starts.)
Is that right?
