Zend_auth and Zend_acl for login authentication and permissions control according to user role have a friend to refer to.
Zend_auth_adapter_interface provides an interface that we need to implement ourselves.
The code is as follows:
| The code is as follows |
Copy Code |
Require_once ' zend/auth/adapter/interface.php ';
Class Auth implements zend_auth_adapter_interface{
Private $_useraccount;
Private $_password;

Public function __construct ($useraccount, $password, $db) {
$this->_useraccount = $useraccount;
$this->_password = $password;
$this->_db = $db;
}
/**

*/
Public function Authenticate ()
{

Explanation: In the implementation code of the Authenticate method, return a Zend_auth_result object instance, and look at the source code of the Zend_auth_result, knowing that the instantiation needs to pass in three parameters:
@param the result of an int $code authentication (for example: zend_auth_result::success)
@param mixed $identity identifiers used for authentication (e.g. login name (Zhang San))
@param array $messages reason for authentication failure
Once the authentication is successful, the information is stored in the session variable.
