What are the potential pitfalls of using multiple sessions in PHP?

Potential pitfalls of using multiple sessions in PHP include increased server resource usage, potential conflicts between sessions, and difficulty in managing multiple sessions for the same user. To avoid these issues, it is recommended to carefully manage session variables and ensure that each session is properly initialized and destroyed when no longer needed. 

// Start a new session or resume the existing session
session_start();

// Set session variables
$_SESSION['user_id'] = 123;

// Destroy the session when it is no longer needed
session_destroy();
