1. 简介
2. 最简单用法
<?php
class AuthController extends Zend_Controller_Action
{
    public function init()
    {
        /* Initialize action controller here */
    }

    public function indexAction()
    {
    echo "Index";
        /* Initialize action controller here */
    }

public function loginAction(){
  echo "Logine";
  $username = "jack";
  $password = "111111";
  $authAdapter = new MyAuthAdapter($username, $password);
  $result = $authAdapter->authenticate();
  if($result->isValid()){
   echo $result->getCode();
  }
}
}
//////实现一个接口,来定义验证适配器
class MyAuthAdapter implements Zend_Auth_Adapter_Interface
{
    /**
     * Sets username and password for authentication
     *
     * @return void
     */     private $name;
    private $pass;

    //决定了验证需要的参数,一般是用户名和密码
    public function __construct($username, $password)
    {
    $this->name=$username;
    $this->pass=$password;
        // ...
    }     /**
     * Performs an authentication attempt
     *
     * @throws Zend_Auth_Adapter_Exception If authentication cannot
     *                                     be performed
     * @return Zend_Auth_Result
     */

    //定义验证方式,一般是字符比照
    public function authenticate()
    {
        echo "Auth:".$this->name;
         echo "Auth:".$this->pass;
         return new Zend_Auth_Result(Zend_Auth_Result::SUCCESS, NULL, array("OK"));
    }
}
?>
///可能的code
Zend_Auth_Result::SUCCESS
Zend_Auth_Result::FAILURE
Zend_Auth_Result::FAILURE_IDENTITY_NOT_FOUND
Zend_Auth_Result::FAILURE_IDENTITY_AMBIGUOUS
Zend_Auth_Result::FAILURE_CREDENTIAL_INVALID
Zend_Auth_Result::FAILURE_UNCATEGORIZED
/// 3. 数据库表认证
    public function authenticate()
    {
      $select=$this->db->select();
         $select->from("student","*");
         $stmt = $this->db->query($select);
   $decry = md5($this->pass);
      $row = $stmt->fetch();
      echo $row['name']."-=-=-=-=-=-".$row['password']."<br>";
         if($this->name == $row['name'] && $decry == $row['password']){
         return new Zend_Auth_Result(Zend_Auth_Result::SUCCESS, NULL, array("OK"));
         }
         else{
         return new Zend_Auth_Result(Zend_Auth_Result::FAILURE_UNCATEGORIZED, NULL, array("NO"));
         }
    }
4. 随机验证码(字母)
$dynamicSalt = "";
  for ($i = 0; $i < 5; $i++)
  {
      $dynamicSalt .= chr(rand(65, 90));
  }
  echo $dynamicSalt;
