FAQs
In PHP, a session is a means to save data for use across numerous pages of an
entire website. Unlike cookies, the information is not kept on the user's machine.
The session will produce a file that stores the registered session variables' values in
a temporary directory on the server. During that visit, this data will be accessible
from every page on the website.When using an application, you open it, make any
necessary changes, and then close it. This is very similar to a session. You are
recognized by the computer. It is aware of when you launch and shut off an
application.However, on the internet, the webserver is unaware of your identity or
your activities.
