Sessions are global variable that can store values and will be accessible throughout the site .The applications that uses session are user login,cart etc . Session values are stored in the server and it will will have reference to a an session id which will be generated when some one call session_start() and will be stored in the local machine

Once the session id created , this id will be passed to the server along with request and with the help of this the code can fect the values stored in  the server .

Session values can be managed with the help of  $_SESSION[] .

Session can be destroyed using the function session_destroy()

Session values will get destroyed if the browser is closed .

$_SESSION[‘lan’]=”PHP Code”;
echo $_SESSION[‘lan’] ;

?>

session php

Session variables are used to store values that are required across multiple web pages .

A website can not remember anything about the users those who have already visited the site since the HTTP request does not have state . But at time , it is necessary to remember some details(eg should understand if a user is logged in or not ) . In such case we can use session that enable the website to store the information for later use .
