如何生成随机密码或临时URL,以便在Zend Framework中重置密码？

$random_bytes = random_bytes(32);
$password_hash = hash('sha256', $random_bytes);

$client = new Zend_Http_Client('http://example.com/temp');
$client->setMethod('POST');
$client->setHeaders('Content-Type: application/x-www-form-urlencoded');
$client->setBody('username=username&password=password');
$response = $client->send();
$temp_url = $response->getBody();

$storage = new Zend_Auth_Storage_Session('auth_session');
$auth = Zend_Auth::getInstance();
$auth->setStorage($storage);
$auth->setIdentity('username', 'password')
     ->setCredential('username', 'password');
if ($auth->hasIdentity()) {
    $temp_url = $auth->getStorage()->read();
} else {
    $temp_url = $auth->getStorage()->write(array('redirect' => 'http://example.com/login'));
}

$view = new Zend_View();
$view->setEncoding('UTF-8');
$view->setSeparator(' - ');
$view->setVariables(array(
    'username' => $temp_url,
    'password' => $temp_url
));
$html = $view->render('login.phtml');
