What potential pitfalls could arise from not using sessions for data transmission in PHP?

Not using sessions for data transmission in PHP can lead to security vulnerabilities such as data interception or tampering. It is recommended to use sessions to securely store and transmit data between pages. 

// Start a session
session_start();

// Store data in session variable
$_SESSION['username'] = 'example_user';

// Retrieve data from session variable
$username = $_SESSION['username'];
