What is the best practice for dynamically generating session variable names in PHP?

When dynamically generating session variable names in PHP, it is best practice to use a consistent naming convention to ensure clarity and organization. One approach is to concatenate a prefix with a unique identifier, such as a user ID or timestamp, to create distinct session variable names. This helps prevent naming conflicts and makes it easier to retrieve and manipulate the session data later on. 

// Example of dynamically generating session variable names with a prefix and unique identifier
$userId = 123; // Unique identifier
$prefix = 'user_'; // Prefix for session variable names

// Creating a session variable with a dynamically generated name
$_SESSION[$prefix . $userId] = 'value';

// Retrieving the session variable using the dynamically generated name
$value = $_SESSION[$prefix . $userId];
