How can the use of session storage for user rights impact performance in PHP applications?

Using session storage for user rights can impact performance in PHP applications because it requires additional server resources to store and retrieve the user rights for each session. To improve performance, consider storing user rights in a more efficient way, such as using database queries to fetch the rights when needed instead of storing them in session storage. 

// Example of fetching user rights from a database instead of using session storage
function getUserRights($userId) {
    // Perform a database query to fetch user rights based on user ID
    // Return the user rights as an array
    return ['read', 'write', 'delete'];
}

// Example of checking user rights in the application
$userId = 1;
$userRights = getUserRights($userId);

if (in_array('write', $userRights)) {
    // User has write permissions, allow access to certain features
} else {
    // User does not have write permissions, restrict access
}
