What are the potential limitations of using boolean algebra for permission management in PHP?

Using boolean algebra for permission management in PHP can be limiting because it can quickly become complex and hard to manage as the number of permissions increases. A more scalable approach would be to use bitwise operations, which allow for more granular control over permissions using a single integer value to represent multiple permissions. 

// Define permissions using bitwise values
define('READ_PERMISSION', 1);
define('WRITE_PERMISSION', 2);
define('DELETE_PERMISSION', 4);

// Check if a user has a specific permission
$userPermissions = READ_PERMISSION | WRITE_PERMISSION; // User has read and write permissions
$requiredPermission = READ_PERMISSION;

if ($userPermissions & $requiredPermission) {
    echo "User has the required permission";
} else {
    echo "User does not have the required permission";
}
