PHP SESSIONS

PHP SESSIONS

• When you work with an application, you open it, do some changes, and then you close it.
• This is much like a Session.
• The computer knows who you are.
• It knows when you start the application and when you end. 
• But on the internet there is one problem.
• The web server does not know who you are or what you do, because the HTTP address doesn't maintain state
• Session variables solve this problem by storing user information to be used across multiple pages.

                           EX : username, favorite color, etc.

DIFFERENT TYPES OF SESSIONS IN PHP :

• Budget session (February to May).
• Monsoon session (July to September).
• Winter session (November to December).

echo ' The Roll number of the student is :' .$_SESSIONS[" Rollnumber "].'<br>';
