4. Set "userid" Session Variable

Write a PHP script to set a session variable named "userid" with the value 10020.

Sample Solution:

PHP Code :

<?php
session_save_path('i:/custom/');
session_start();

$_SESSION["userid"] = 10020;

echo "Session variable 'userid' has been set with the value 10020.";
?>

Sample Output:

Session variable 'userid' has been set with the value 10020.

Explanation:

In the above exercise -

The code starts with session_save_path('i:/custom/'). This line sets a custom path (i:/custom/) for storing session files. You should replace i:/custom/ with the actual path where you want to store session files.
The code then calls session_start(). This function initializes a new or existing session.
After starting the session, the code assigns the value 10020 to the session variable named "userid" using $_SESSION["userid"] = 10020;.
Finally, the code uses echo to display the message "Session variable 'userid' has been set with 10020.".
