How can usernames be transferred between PHP files using sessions?

To transfer usernames between PHP files using sessions, you can store the username in a session variable in one PHP file and then access it in another PHP file. This allows you to maintain the username's value across different pages during a user's session on the website. 

// File 1: store_username.php
session_start();
$username = "example_username";
$_SESSION['username'] = $username;

// File 2: retrieve_username.php
session_start();
$username = $_SESSION['username'];
echo "Welcome, $username!";
