In php, Zend_Auth and Zend_Acl are used for logon authentication and permission control based on user roles (14 ). Zend_Auth and Zend_Acl are used for logon authentication and permission control based on user roles. For more information, see. Zend_Auth_Adapter_Interface provides an interface. we need to perform logon authentication from Zend_Auth and Zend_Acl and perform permission control based on the user role. For more information, see.
Zend_Auth_Adapter_Interface provides an interface, which needs to be implemented by ourselves.
The code is as follows:
| The code is as follows: |
|
Require_once 'zend/Auth/Adapter/Interface. php ';
Class Auth implements Zend_Auth_Adapter_Interface {
Private $ _ useraccount;
Private $ _ password;

Explanation: In the implementation code of the authenticate method, return a Zend_Auth_Result object instance, and view the source code of Zend_Auth_Result. it is known that three parameters need to be input during instantiation:
@ Param int $ code ID authentication result (for example, Zend_Auth_Result: SUCCESS)
@ Param mixed $ identity indicates the identity used for identity authentication (for example, logon name (John ))
@ Param array $ array of causes of messages authentication failure
Once the authentication succeeds, the information is stored in the session variable.
