How session works (internal processing of session) ?..

To start a session:
– session_start()
– Creates a session identifier
– Session identifier is passed between client and server
either as
a Cookie, or in GET parameters
• Then, can create, access, and modify session variables:
– $_SESSION[session_var_name] = value;
– $_SESSION is only available once you call session_start()
– $local_variable = $_SESSION[session_var_name];
– Can check if session variable is set by using isset();
• To end a session:
– session_destroy();
