How Sessions work in PHP

How Sessions are created is it between web server and browser or something else and from where it will take session time period

Thanks in Advacne

 

Sessions are created by the server (session_start() and stored on the server, the user simply has a session ID which allows the server to know where to look to call up the temporary file that's holding the data.

Shortly session is a Memory machine, You can Store Some value in session and you can use it when you want it(Before they expire), It is procedure in your server (session data stored in server) so visitor (From client browser )cannot hack what value stored in session.

 

Thank You for the reply

sessions after sometime expire and again it will ask for login, so how the time period is consider is it consider at what time a user login or it takes server time

 

Why not use cookies, you can set time for 1 hours, 1 days , 1 weeks or as your wish

 

Session is Global Variable that stored in Server.
for example, session is used to "Log In"
