How can the issue of session overwriting be resolved when multiple users are accessing a PHP application?

Session overwriting can be resolved by using unique session IDs for each user accessing the PHP application. This can be achieved by setting the session name to a unique value for each user, such as their user ID or a random string. By ensuring that each user has a distinct session ID, data for each user can be stored and retrieved without being overwritten by other users' session data. 

<?php
// Start the session
session_start();

// Generate a unique session ID for each user
$unique_session_id = $_SESSION['user_id']; // or any other unique identifier

// Set the session name to the unique session ID
session_name($unique_session_id);

// Now you can store and retrieve data specific to each user without overwriting session data
$_SESSION['user_data'] = "User-specific data";
?>
