Zend Framework

Prepared By: Er. Vishanta R vishanta.rayamajhi@gmail.com

Zend Framework: Introduction Zend Framework is based on simplicity, object-oriented best practices, corporate friendly licensing, and a rigorously tested agile codebase. Zend Framework is focused on building more secure, reliable, and modern Web 2.0 applications & web services, and consuming widely available APIs from leading vendors like google, amazon, flickr as well as API providers.

Frameworks and best practices mean reduced training costs and quicker timeto-market – important factors in adoption decisions. Built so you can pick and choose just the pieces you need to turbocharge your web applications – all your developers know where to find their PHP / Zend Framework code, speeding new development and reducing maintenance costs.

Zend Framework also provides an advanced model-view-controller (MVC) implementation that can be used to establish a basic structure for your ZF applications.

Model- View-Controller : ďƒ˜

Model - This is the part of your application that defines its basic functionality behind a set of abstractions. Data access routines and some business logic can be defined in the model.

ďƒ˜

View - Views define exactly what is presented to the user. Usually controllers pass data to each view to render in some format. Views will often collect data from the user, as well. This is where you're likely to find HTML markup in your MVC applications.

ďƒ˜

Controller - Controllers bind the whole pattern together. They manipulate models, decide which view to display based on the user's request and other factors, pass along the data that each view will need, or hand off control to another controller entirely. Most MVC experts recommend keeping controllers as skinny as possible.

Few Properties of Zend Framework are : Extreme Simplicity & Productivity Zend Framework is designed with simplicity in mind. To provide a lightweight, loosely-coupled component library simplified to provide the functionality everyone needs and that lets you customize the other 20% to meet your specific business needs. By focusing on the most commonly needed functionality, we retain the simplified spirit of PHP programming, dramatically lower the learning curve, and your training costs – so developers get up-to-speed quickly.

Zend Components : Model-View-Controller (MVC) 

Zend_Controller, Zend_Controller_Action, Zend_Controller_Dispatcher, Zend_Controller_Plugin, Zend_Controller_RewriteRouter, Zend_View



Zend_Http_Request, Zend_Http_Response The above components make use of the industry standard web application design pattern MVC (which originated with one of the first scripting languages ever built, Smalltalk), and allows developers and web designers to separate their concerns and skills, making code implementation and design easily and clearly separated. No more confusion or needing both skill sets in one person.

Database Zend_Db Zend_Db_Table Internationalization (i18n) and Localization (l10n) Zend_Date Zend_Locale Zend_Measure Zend_Translate In an increasingly global economy, localizing your application for a particular language and culture is imperative, not an afterthought. Do that easily, whenever you're ready to expand your markets, with Zend Framework's support for internationalization (i18n).

Authentication, Authorization, and Session management Zend_Acl  Zend_Authentication  Zend_Session  Virtually all web applications have some user-specific data that must be customized, and usually, protected from access by other users. Accomplish this quickly and easily with the above features of Zend Framework.

Web and Web Services Consuming services: Zend_Feed, Zend_Rest_Client, Zend_Service, Zend_XmlRpc_Client,  Zend_Gdata, Zend_Http_Client Exposing services: Zend_Http_Server, Zend_Rest_Server, Zend_Server_Documentor,  Zend_Server_Reflection, Zend_Soap_Server, Zend_XmlRpc_Server Zend_Uri  Web services are an integral part of Zend Framework and we intend for Zend Framework to be the nexus for and entire eco-system of Web Services and APIs providers. We currently have partnered with Google, Microsoft, and StrikeIron and they have built support for their services into Zend Framework. More are coming soon.

Mail, Formats, and Search Zend_Json, Zend_Pdf  Zend_Mail, Zend_Mime  Zend_Search_Lucene 

Web 2.0 applications require support for Ajax, PDF generation, e-mail communication, and search, all an increasingly important part of web applications today. Zend Framework simplifies a developers life and gives you built-in support for these essential, if not critical, features for your application.

Core Infrastructure  Zend_Cache, Zend_Config, Zend_Console_Getopt, Zend_Log, Zend_Memory  Zend_Debug, Zend_Environment, Zend_Loader, Zend_Registry, Zend_Version  Zend_Filter, Zend_Validate Zend Framework is a broad library of loosely-coupled, yet highly cohesive pieces that support many of the other features you might need for a web application.

From logging for tracking and debugging your application in production, caching for high performance, filtering for more secure and safe applications, to all the other little pieces that make a web application developer's life easy, Zend Framework provides all this, plus a vast community, a company standing behind and sponsoring development, and a large number of talented developers who know how to build Zend Framework applications from the ground up.

Zend API: PHP can be extended primarily at three points: external modules, built-in modules, and the Zend engine. The following sections discuss these options.

External Modules External modules can be loaded at script runtime using the function dl(). This function loads a shared object from disk and makes its functionality available to the script to which it's being bound. After the script is terminated, the external module is discarded from memory. This method has both advantages and disadvantages, as described in the following table:

Advantages External modules don't require recompiling of PHP.

Disadvantages The shared objects need to be loaded every time a script is being executed (every hit), which is very slow.

Advantages The size of PHP remains small by "outsourcing" certain functionality.

Disadvantages External additional files clutter up the disk.

Every script that wants to use an external module's functionality has to specifically include a call to dl(), or the extension tag in php.ini needs to be modified (which is not always a suitable solution).

To sum up, external modules are great for third-party products, small additions to PHP that are rarely used, or just for testing purposes. To develop additional functionality quickly, external modules provide the best results. For frequent usage, larger implementations, and complex code, the disadvantages outweigh the advantages.

Third parties might consider using the extension tag in php.ini to create additional external modules to PHP. These external modules are completely detached from the main package, which is a very handy feature in commercial environments.

Commercial distributors can simply ship disks or archives containing only their additional modules, without the need to create fixed and solid PHP binaries that don't allow other modules to be bound to them.

Built-in Modules Built-in modules are compiled directly into PHP and carried around with every PHP process; their functionality is instantly available to every script that's being run.

Like external modules, built-in modules have advantages and disadvantages, as described in the following table:

Advantages

Disadvantages

No need to load the module specifically; the functionality is instantly available.

Changes to built-in modules require recompiling of PHP.

No external files clutter up the disk; everything resides in the PHP binary.

The PHP binary grows and consumes more memory.

Built-in modules are best when you have a solid library of functions that remains relatively unchanged, requires better than poor-to-average performance, or is used frequently by many scripts on your site. The need to recompile PHP is quickly compensated by the benefit in speed and ease of use. However, built-in modules are not ideal when rapid development of small additions is required.

The Zend Engine Of course, extensions can also be implemented directly in the Zend engine. This strategy is good if you need a change in the language behavior or require special functions to be built directly into the language core. In general, however, modifications to the Zend engine should be avoided. Changes here result in incompatibilities with the rest of the world, and hardly anyone will ever adapt to specially patched Zend engines. Modifications can't be detached from the main PHP sources and are overridden with the next update using the "official" source repositories. Therefore, this method is generally considered bad practice.

Using Yahoo! APIs With the Zend Framework Zend_Service_Yahoo is a simple API for using many of the Yahoo! REST APIs. Zend_Service_Yahoo allows you to search Yahoo! Web search, Yahoo! News, Yahoo!
