Zend_Cache - "数据必须是字符串或设置automatic_serialization = true"

Question

我试图用Zend_Cache缓存一个数组,如下所示:

$cache = Zend_Registry::get('cache');
// $data is an array
$cache->save($data, 'externalData');

我收到这个错误:

Message: Datas must be string or set automatic_serialization = true

即使在bootstrap文件中初始化Zend_Cache时设置了true_serialization:

protected function _initCache()
{
    $frontend= array('lifetime' => 7200,
                     'automatic_seralization' => true);
    $backend= array('cache_dir' => 'cache');
    $this->cache = Zend_Cache::factory('core',
                                       'File',
                                       $frontend,
                                       $backend);
}

什么可能导致此错误消息？

Answer 1

也许您只是制作了复制粘贴错误或拼写错误,但是,在您发布的代码中,您有:

$frontend= array('lifetime' => 7200,
                 'automatic_seralization' => true);

即要设置automatic_seralization为true,而不是automatic_serialization:注意我在丝氨酸我 -alization.
