        'display_not_found_reason' => true,//false关闭错误提示
        'display_exceptions'       => true,//false关闭错误提示
    ),

19.zend framework 2 加载modules、config配置文件太多，如何提高性能速度？

configapplication.config.php

<?php
return array(
    // This should be an array of module namespaces used in the application.
    'modules' => array(
        'Application',
    ),

    // These are various options for the listeners attached to the ModuleManager
    'module_listener_options' => array(
        // This should be an array of paths in which modules reside.
        // 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.
        'config_glob_paths' => array(
            'config/autoload/{,*.}{global,local}.php',
        ),

        // Whether or not to enable a configuration cache.
        // If enabled, the merged configuration will be cached and used in
        // subsequent requests.
        'config_cache_enabled' => true,

        // The key used to create the configuration cache file name.
        'config_cache_key' => 'key',

        // Whether or not to enable a module class map cache.
        // If enabled, creates a module class map cache which will be used
        // by in future requests, to reduce the autoloading process.
        'module_map_cache_enabled' => true,

        // The key used to create the class map cache file name.
        'module_map_cache_key' => 'key',
        

        // The path in which to cache merged configuration.
        'cache_dir' => './data/cache',

        // Whether or not to enable modules dependency checking.
        // Enabled by default, prevents usage of modules that depend on other modules
        // that weren't loaded.
         'check_dependencies' => true,
    ),

    // Used to create an own service manager. May contain one or more child arrays.
    //'service_listener_options' => array(
    //     array(

    //     ),
    // )

   // Initial configuration with which to seed the ServiceManager.
   // Should be compatible with ZendServiceManagerConfig.
   // 'service_manager' => array(),
);

21.如何把ZF2库 移动到public外面WEB访问不到的目录，以确保安全？

/init_autoloader.php

$zf2Path = false;


替换为你的ZF2库的真实路径，如：


$zf2Path = '../../zf-2.3.2/library';

22.如何让zend framework 2 在访问时，末尾不加斜线/和加斜线/都不报错达到兼容？

'may_terminate' => true,
                'child_routes' => array(
                    'default' => array(
                        'type'    => 'Segment',
                        'options' => array(
                            'route'    => '/[:controller[/:action]][/]',
                            'constraints' => array(
                                'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
                                'action'     => '[a-zA-Z][a-zA-Z0-9_-]*',
                            ),
                            'defaults' => array(
                            ),
                        ),
                    ),
                ),

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：

configautoloadview_helpers.global.php

<?php
return array(
    'view_helpers' => array(
        'invokables' => array(
            'ConfigHelper' => 'ApplicationViewHelperConfigHelper'
        )
    )
);

新建文件：

moduleApplicationsrcApplicationViewHelperConfigHelper.php

<?php
namespace ApplicationViewHelper;

use ZendViewHelperAbstractHelper;

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：

configautoloadcontroller_plugins.global.php

<?php
return array(
    'controller_plugins' => array(
        'invokables' => array(
            'myPlugin' => 'ApplicationControllerPluginMyPlugin'
        )
    )
);

新建文件：

moduleApplicationsrcApplicationControllerPluginMyPlugin.php

<?php
namespace ApplicationControllerPlugin;

use ZendMvcControllerPluginAbstractPlugin;

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，

datacachemodule-classmap-cache.key.php

datacachemodule-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：

configautoloadcache.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(
            'ZendCacheStorageAdapterFilesystem' => 'ApplicationServiceFilesystemCacheService',
            'ZendCacheStorageAdapterMemcached' => 'ApplicationServiceMemcachedCacheService'
        )
    )
);

新建文件：

moduleApplicationsrcApplicationServiceFilesystemCacheService.php

<?php
namespace ApplicationService;

use ZendServiceManagerFactoryInterface;
use ZendServiceManagerServiceLocatorInterface;

class FilesystemCacheService implements FactoryInterface
{

    public function createService(ServiceLocatorInterface $sm)
    {
        $cache = endCacheStorageFactory::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：

moduleApplicationsrcApplicationServiceMemcachedCacheService.php

<?php
namespace ApplicationService;

use ZendServiceManagerFactoryInterface;
use ZendServiceManagerServiceLocatorInterface;

class MemcachedCacheService implements FactoryInterface
{

    public function createService(ServiceLocatorInterface $sm)
    {
        $config = $sm->get('config');
        $cache = endCacheStorageFactory::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 = $this->controller->getServiceLocator()->get('ZendCacheStorageAdapterFilesystem');
//$cache = $this->controller->getServiceLocator()->get('ZendCacheStorageAdapterMemcached');//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：

configautoloadcontroller_plugins.global.php

<?php
return array(
    'controller_plugins' => array(
        'invokables' => array(
            'PaginatorPlugin' => 'ApplicationControllerPluginPaginatorPlugin'
        )
    )
);

新建文件：

moduleApplicationsrcApplicationControllerPluginPaginatorPlugin.php


<?php
namespace ApplicationControllerPlugin;

use ZendMvcControllerPluginAbstractPlugin;
use ZendPaginatorAdapterDbSelect;
use ZendPaginatorPaginator;
use ZendDbSqlSql;

class PaginatorPlugin extends AbstractPlugin {
	public function getResults($table, array $columns = array('*')) {
	    
		$sql = new Sql ($this->controller->getServiceLocator()->get('ZendDbAdapterAdapter'));
		$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：

moduleApplicationviewpageglobal.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！

moduleApplicationsrcApplicationViewHelperConfigHelper.php

<?php
namespace ApplicationViewHelper;

use ZendViewHelperAbstractHelper;
use ZendServiceManagerServiceLocatorAwareInterface;

class ConfigHelper extends AbstractHelper implements ServiceLocatorAwareInterface
{
    use endServiceManagerServiceLocatorAwareTrait;
    
    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！

moduleApplicationsrcApplicationControllerPluginMyPlugin.php


<?php
namespace ApplicationControllerPlugin;

use ZendMvcControllerPluginAbstractPlugin;

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;
    }
}

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

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