25.zend framework 2 如何使用文件缓存和内存缓存Memcached、APC等相关问题解答

zend framework 2 开启配置文件缓存application.config.php下的

?
1
2
3
'config_cache_enabled'=> true,
 
'module_map_cache_enabled'=> true,

时，这时会生成2个zend framework 2配置文件缓存文件，

?
1
2
3
\data\cache\module-classmap-cache.key.php
 
\data\cache\module-config-cache.key.php

同时，如果在zend framework 2的config配置文件使用匿名函数时，这时就会报错（不使用匿名函数或者不开启配置文件缓存都没事，同时使用就报错，ZF2的Bug）：

?
1
Fatal error: Call to undefined method Closure::__set_state()

26.如何解决Fatal error: Call to undefined method Closure::__set_state()错误Bug？

?
1
不使用匿名函数，使用service_manager服务管理器！

这时，清空你的配置文件缓存，Controller、Plugin里直接使用缓存的方法：

$key = 'yourKey...';
$cache = $this->controller->getServiceLocator()->get('Zend\Cache\Storage\Adapter\Filesystem');
//$cache = $this->controller->getServiceLocator()->get('Zend\Cache\Storage\Adapter\Memcached');//Memcached
$cacheResults= $cache->getItem($key,$success);
             
if($success== true){
return unserialize($cacheResults);
}else{
$cache->setItem($key, serialize('保存你的结果数据到你的缓存...'));
}

Controller中直接使用：
 
 
$paginator= $this->PaginatorPlugin()->getResults('你的表的名称');
$paginator->setCurrentPageNumber((int)$this->params()->fromQuery('p', 1));
$paginator->setItemCountPerPage(10);
         
return new ViewModel(array('paginator'=> $paginator));

Controller 的 Action 对应的模板：

var_dump($v);
}
}
?>
 
 
<?php echo$this->paginationControl($this->paginator,'sliding', 'page/global.phtml', array('route'=> 'application'));//分页列表?>

\module\Application\src\Application\View\Helper\ConfigHelper.php
 
<?php
namespace Application\View\Helper;
 
use Zend\View\Helper\AbstractHelper;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
 
class ConfigHelper extends AbstractHelper implements ServiceLocatorAwareInterface
{
    use\Zend\ServiceManager\ServiceLocatorAwareTrait;
     
    publicfunction getPath(){
        return$this->getServiceLocator()->getServiceLocator()->get('ControllerPluginManager')->get('插件的class名称')->插件方法名();
    }
}

模板中直接使用视图助手：

?

<?php echo$this->ConfigHelper()->getPath();?>

tips：与上同理，举一反三，如何在插件中使用ServiceManager服务管理器调用其它插件或者其它视图助手，也是一样的原理！

30.zend framework 2 如何在ACTION中优雅的输出Module名称、Controller名称、Action名称 ?

<?php
namespace Application\Controller\Plugin;
 
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
 
class MyPlugin extends AbstractPlugin {
     
    publicfunction getPath($type= false){
        $path= explode('/',str_ireplace('\Controller\\','/', $this->controller->params('controller')) .'/' . $this->controller->params('action'));
        switch($type) {
            case'm'://module
                returnstrtolower($path[0]);
                break;
            case'c'://controller
                returnstrtolower($path[1]);
                break;
            case'a'://action
                returnstrtolower($path[2]);
            break;
            case'mc'://module/controller
                returnstrtolower($path[0].'/'.$path[1]);
            break;
            default:
                returnstrtolower(join('/',$path));//all
            break;
        }
        return$path;
    }
}

Controller的indexAction中直接输出Module名称、Controller名称、Action名称即可！

var_dump($this->MyPlugin()->getPath());
