本文实例讲述了Zend Framework教程之资源(Resources)用法。分享给大家供大家参考,具体如下:
Zend_Application_Resource_Resource
Zend_Application_Bootstrap_ResourceBootstrapper是引导类加载注册资源插件使用的接口。
Zend_Application_Resource_Resource是一个资源插件接口。
Zend_Application_Resource_Resource通常被用于实现了Zend_Application_Bootstrap_ResourceBootstrapper的引导类中。
资源插件是一个可配置,预加载的和可以通过策略模式初始化资源的接口。
Zend_Application_Resource_Resource Interface
Method | Return Value | Parameters | Description |
---|---|---|---|
__construct($options = null) | Void |
|
|
setBootstrap(Zend_Application_Bootstrap_Bootstrapper $bootstrap) | Zend_Application_Resource_Resource |
|
|
getBootstrap() | Zend_Application_Bootstrap_Bootstrapper | N/A |
|
setOptions(array $options) | Zend_Application_Resource_Resource |
|
|
getOptions() | Array | N/A |
|
init() | Mixed | N/A |
采用策略模式: 运行,初始化资源. |
Zend_Application_Resource_ResourceAbstract
Zend_Application_Resource_ResourceAbstract是一个抽象类,实现了Zend_Application_Resource_Resource接口,为创建自定义插件资源提供了一个便捷的方式。
注:这个抽象类没有实现init()方法,可以继承使用这个抽象类,自定义实现init方法。
Zend_Application_Resource_ResourceAbstract Methods
Method | Return Value | Parameters | Description |
---|---|---|---|
__construct($options = null) | Void |
|
|
setBootstrap(Zend_Application_Bootstrap_Bootstrapper $bootstrap) | Zend_Application_Resource_ResourceAbstract |
|
|
getBootstrap() | Zend_Application_Bootstrap_Bootstrapper | N/A |
|
setOptions(array $options) | Zend_Application_Resource_ResourceAbstract |
|
|
getOptions() | Array | N/A |
|
资源名称
注册插件资源时,出现的一个问题是你应该如何从父引导类。有三种不同的机制,可以使用,这取决于你是如何配置的引导和它的插件资源。
首先,如果你的插件名称定义包含前缀路径,您可以通过他们的“短名称” - 即类的名称的一部分。例如,类“Zend_Application_Resource_View”的短名称是“View”,如果前缀路径“Zend_Application_Resource”已注册。您可能使用类的全名或短名称注册他们:
$app = new Zend_Application(APPLICATION_ENV, array( 'pluginPaths' => array( 'My_Resource' => 'My/Resource/', ), 'resources' => array( // if the following class exists: 'My_Resource_View' => array(), // then this is equivalent: 'View' => array(), ), ));
以后可以使用短名称引导资源和获取:
$bootstrap->bootstrap('view'); $view = $bootstrap->getResource('view');
其次,如果没有匹配的插件路径的定义,你可能仍然通过使用资源类的全名。在这种情况下,你可以参考如下使用资源的完整类名:
$app = new Zend_Application(APPLICATION_ENV, array( 'resources' => array( // This will load the standard 'View' resource: 'View' => array(), // While this loads a resource with a specific class name: 'My_Resource_View' => array(), ), ));
引导资源以及获取方式
$bootstrap->bootstrap('My_Resource_View'); $view = $bootstrap->getResource('My_Resource_View');
这给我们带来了第三个选项。您可以指定一个明确的名称,将自己注册为一个给定的资源类。这可以通过资源插件类增加 public $_explicitType的字符串值,该值将被用来指定引导插件资源。作为一个例子,让我们来定义我们自己的视图类:
class My_Resource_View extends Zend_Application_Resource_ResourceAbstract { public $_explicitType = 'My_View'; public function init() { // do some initialization... } }
然后,我们可以引导资源或通过它的名字“My_View”获取:
$bootstrap->bootstrap('My_View'); $view = $bootstrap->getResource('My_View');
可以使用这些不同的命名方法,覆盖现有资源,添加您自己的,混合是i用多种资源,以实现复杂的初始化等等。

希望本文所述对大家PHP程序设计有所帮助。

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
