How can PHP developers effectively integrate database-driven permission management with Zend ACL for improved scalability and maintainability?

To effectively integrate database-driven permission management with Zend ACL for improved scalability and maintainability, PHP developers can create a custom resource class that fetches permissions from the database and dynamically adds them to the ACL. This allows for easy management of permissions without the need to modify code every time a new permission is added or updated. 

// Custom resource class to fetch permissions from the database
class DbResource implements Zend_Acl_Resource_Interface
{
    protected $db;

    public function __construct($db)
    {
        $this->db = $db;
    }

    public function getPermissions()
    {
        // Fetch permissions from the database
        $permissions = $this->db->query('SELECT * FROM permissions')->fetchAll();

        foreach ($permissions as $permission) {
            $this->addPermission($permission['resource'], $permission['privilege']);
        }
    }

    public function addPermission($resource, $privilege)
    {
        // Add permission to the ACL
        $acl->addResource(new Zend_Acl_Resource($resource));
        $acl->allow($role, $resource, $privilege);
    }
}

// Implementation
$db = new PDO('mysql:host=localhost;dbname=permissions', 'username', 'password');
$resource = new DbResource($db);
$resource->getPermissions();
