PHP SESSIONS
A session variable is used to store the information about or change the settings for a user session.
Session variables hold information about one single user and are all variables to all pages in one application.
When the user working with applications, the user wants to open it and make the changes and the user want to close it.The session is also a server side temporary memory storage.
The web browser is don't know who is the user and the what the user can do because the HTTP
Protocol has not maintained the state.
The maximum lifetime of the session is 1440 seconds.We can able to change the time using
ini_set('session.gc_maxlifetime', 3600)
Example:
<?php
session_start();
?>
<html>
<body>
<?php
$_SESSION["favcricketer"]= "Tendulkar";
$_SESSION["favcar"]= "BMW";
echo "Session variables are set."
?>
</body>
</html>
Output:
Session variables are set.
