),
19.zend framework 2 加载modules、config配置文件太多，如何提高性能速度？
\config\application.config.php
<?php
return array(
// This should be an array of module namespaces used in the application.

// If a string key is provided, the listener will consider that a module
// namespace, the value of that key the specific path to that module's
// Module class.
'module_paths' => array(
'./module',
'./vendor',
),
// An array of paths from which to glob configuration files after
// modules are loaded. These effectively override configuration
// provided by modules themselves. Paths may use GLOB_BRACE notation.

23.zend framework 2 如何在模板中轻松引入Modules、Controller、View都可以访问的方法，是view_helpers么？
新建文件：
\config\autoload\view_helpers.global.php
<?php
return array(
'view_helpers' => array(
'invokables' => array(
'ConfigHelper' => 'Application\View\Helper\ConfigHelper'
)
)
);
新建文件：
\module\Application\src\Application\View\Helper\ConfigHelper.php
<?php
namespace Application\View\Helper;
use Zend\View\Helper\AbstractHelper;
class ConfigHelper extends AbstractHelper
{
public $hello = array(
1 => 'http://my.oschina.net/cart/blog/174571',
2 => 'http://my.oschina.net/cart/'
);
public function test($key){
return $key;
}
}
模板中调用：
var_dump($this->ConfigHelper()->hello);
var_dump($this->ConfigHelper()->test('http://my.oschina.net/cart/'));
Modules、Controller中就像 引入常规类文件 class 一样，这里就不再赘述
24.zend framework 2 如何引入我自己写的插件controller_plugins？
新建文件：
\config\autoload\controller_plugins.global.php
<?php
return array(
'controller_plugins' => array(
'invokables' => array(
'myPlugin' => 'Application\Controller\Plugin\MyPlugin'
)
)
);
新建文件：
\module\Application\src\Application\Controller\Plugin\MyPlugin.php
<?php
namespace Application\Controller\Plugin;
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
class MyPlugin extends AbstractPlugin {
public function getResults($key) {
return $key;
}
}
Controller中使用：
var_dump($this->MyPlugin()->getResults('hello,http://my.oschina.net/cart/'));
Moudle中使用：
var_dump($serviceLocator->get('ControllerPluginManager'))->get('MyPlugin')->getResults('hello,http://my.oschina.net/cart/');
var_dump($sm->get('ControllerPluginManager'))->get('MyPlugin')->getResults('hello,http://my.oschina.net/cart/');
var_dump($this->controller->getServiceLocator()->get('ControllerPluginManager'))->get('MyPlugin')->getResults('hello,http://my.oschina.net/cart/');
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
'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，
\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）：
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？
不使用匿名函数，使用service_manager服务管理器！
27.如何使用ZF2 service_manager 服务管理器？
=============================================
新建文件：
\config\autoload\cache.global.php
<?php
return array(
'Filesystem' => array(
'cache_dir' => './data/cache',
'namespace' => 'Filesystem',
'dir_level' => 2,
'filePermission' => 0666,
'dirPermission' => 0755,
'ttl' => 3600,
'clear_stat_cache' => true,
'file_locking' => true
),
'Memcached' => array(
'lifetime' => 3600,
'options' => array(
'servers' => array(
array('127.0.0.1', 11211)
),
'namespace' => 'Memcached',
'liboptions' => array(
'COMPRESSION' => true,
'binary_protocol' => true,
'no_block' => true,
'connect_timeout' => 100
)
)
),
'service_manager' => array(
'factories' => array(
'Zend\Cache\Storage\Adapter\Filesystem' => 'Application\Service\FilesystemCacheService',
'Zend\Cache\Storage\Adapter\Memcached' => 'Application\Service\MemcachedCacheService'
)
)
);
新建文件：
\module\Application\src\Application\Service\FilesystemCacheService.php
<?php
namespace Application\Service;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class FilesystemCacheService implements FactoryInterface
{
public function createService(ServiceLocatorInterface $sm)
{
$cache = \Zend\Cache\StorageFactory::factory(array(
'adapter' => 'filesystem',
'plugins' => array(
'exception_handler' => array(
'throw_exceptions' => false
),
'serializer'
)
));
$config = $sm->get('config');
$cache->setOptions($config['Filesystem']);
return $cache;
}
}
新建文件：
\module\Application\src\Application\Service\MemcachedCacheService.php
<?php
namespace Application\Service;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class MemcachedCacheService implements FactoryInterface
{
public function createService(ServiceLocatorInterface $sm)
{
$config = $sm->get('config');
$cache = \Zend\Cache\StorageFactory::factory(array(
'adapter' => array(
'name' => 'memcached',
'lifetime' => $config['Memcached']['lifetime'],
'options' => $config['Memcached']['options']
),
'plugins' => array(
'exception_handler' => array(
'throw_exceptions' => false
)
)
));
return $cache;
}
}
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...'));
}
28.zend framework 2 分页功能如何实现Paginator教程DEMO？
新建文件：
\config\autoload\controller_plugins.global.php
<?php
return array(
'controller_plugins' => array(
'invokables' => array(
'PaginatorPlugin' => 'Application\Controller\Plugin\PaginatorPlugin'
)
)
);
新建文件：
\module\Application\src\Application\Controller\Plugin\PaginatorPlugin.php
<?php
namespace Application\Controller\Plugin;
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
use Zend\Paginator\Adapter\DbSelect;
use Zend\Paginator\Paginator;
use Zend\Db\Sql\Sql;
class PaginatorPlugin extends AbstractPlugin {
public function getResults($table, array $columns = array('*')) {
$sql = new Sql ($this->controller->getServiceLocator()->get('Zend\Db\Adapter\Adapter'));
$select = $sql->select($table);
$select->columns($columns);
$paginatorAdapter = new DbSelect($select, $sql);
$paginator = new Paginator($paginatorAdapter);
return $paginator;
}
}
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' => $paginator));
Controller 的 Action 对应的模板：
<?php
foreach($this->paginator as $value){
foreach ($value as $k => $v) {//输出数据库中的内容
var_dump($k);
echo '<hr>';
var_dump($v);
}
}
?>
<?php echo $this->paginationControl($this->paginator, 'sliding', 'page/global.phtml', array('route' => 'application'));//分页列表?>
新建文件： \module\Application\view\page\global.phtml <?php if ($this->pageCount): ?> <div class="text-right"> <ul class="pagination"> <?php if (isset($this->previous)): ?> <li><a href="<?php echo $this->url($this->route); ?>?p=<?php echo $this->previous; ?>"> << </a></li> <?php else: ?> <li class="disabled"><a href="javascript:;"> << </a></li> <?php endif; ?> <?php foreach ($this->pagesInRange as $page): ?> <?php if ($page != $this->current): ?> <li><a href="<?php echo $this->url($this->route);?>?p=<?php echo $page; ?>"><?php echo $page; ?></a></li> <?php else: ?> <li class="active"><a href="javascript:;"><?php echo $page; ?></a></li> <?php endif; ?> <?php endforeach; ?> <?php if (isset($this->next)): ?> <li><a href="<?php echo $this->url($this->route); ?>?p=<?php echo $this->next; ?>"> >> </a></li> <?php else: ?> <li class="disabled"><a href="javascript:;"> >> </a></li> <?php endif; ?> </ul> </div> <?php endif; ?>
29.zend framework 2 如何在视图助手ViewHelper中执行插件Controller Plugin?
首先你要知道创建视图助手ViewHelper和创建插件Controller Plugin，这里就不再赘述！
\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;
public function 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 $this->ConfigHelper()->getPath();?>
tips：与上同理，举一反三，如何在插件中使用ServiceManager服务管理器调用其它插件或者其它视图助手，也是一样的原理！
30.zend framework 2 如何在ACTION中优雅的输出Module名称、Controller名称、Action名称 ?
这里 我们采取插件的方式来实现zend framework 2 的ACTION输出Module名称、Controller名称、Action名称
首先你要知道如何创建插件Controller Plugin，这里就不再赘述！
\module\Application\src\Application\Controller\Plugin\MyPlugin.php
<?php
namespace Application\Controller\Plugin;
use Zend\Mvc\Controller\Plugin\AbstractPlugin;
class MyPlugin extends AbstractPlugin {
public function getPath($type = false){
$path = explode('/', str_ireplace('\Controller\\', '/', $this->controller->params('controller')) . '/' . $this->controller->params('action'));
switch ($type) {
case 'm'://module
return strtolower($path[0]);
break;
case 'c'://controller
return strtolower($path[1]);
break;
case 'a'://action
return strtolower($path[2]);
break;
case 'mc'://module/controller
return strtolower($path[0].'/'.$path[1]);
break;
default:
return strtolower(join('/', $path));//all
break;
}
return $path;
}
}
var_dump($this->MyPlugin()->getPath());
