ZF Zend Framework

There are lots of ways to contribute to Zend Framework. Many major features are contributed to ZF through our proposal process. Many code contributors also commit bug fixes and tests. Another valuable form of contribution is manual translation. Contributors may also invest their time in updating the wiki or adding, commenting on, and voting on issues in our issue tracker. No matter how you plan to contribute, the best place to get started is our contributor guide.

You're probably looking for decorators. All forms and form elements in Zend_Form use decorators to render their output.

This can easily be done using decorators. For instance using the Description decorator. It is important to note though that you will need to turn off escaping for the output of the decorator:

Now, you can use the following to add extra HTML to the element:

Zend Framework was built to use all of the advanced object oriented features of PHP 5. Since PHP 4 is not fully forwards compatible with PHP 5, the Zend Framework community was faced with the decision of committing to support PHP 4 or leveraging existing and future enhancements in PHP 5 from the outset. We felt the overall value proposition was tipped in favor of PHP 5 feature, performance, and security enhancements. On top of that, PHP 4 is officially unsupported by the PHP community as of 2008-01-01, and no critical security updates will be published after 2008-08-08.

Unlike the view and the controller components, the model component can vary dramatically in responsibilities and data store from one MVC application to the next. The ZF community has not defined a model interface, class, or other formalism simply because we wanted to avoid introducing limitations without significant added value. With the introduction of Zend_Form in ZF 1.5, there is potential added value in form-model interoperability. We will evaluate proposals for models which facilitate this interoperability while supporting all data backends for future inclusion in the standard library.

Both. Zend Framework provides all the components required for most web applications in a single distribution. But Zend Framework components are also loosely coupled, making it easier to use just a few components to provide functionality to a web application- even alongside other frameworks! With this use-at-will architecture we are implementing features commonly found in more monolithic frameworks. In fact, we are currently working on a tooling component that will make it simpler to build applications using ZF components, yet will not sacrifice the use-at-will nature of existing ZF components. In fact, the tooling component itself can be used alone.

By default, ZF uses an action helper called the ViewRenderer. This action helper instantiates and stores a Zend_View object which is injected into various other objects. To get the ViewRenderer, pull it from the Action Helper broker:

The view object is stored in the ViewRenderer's view property:

However, if you're grabbing the view early in the dispatch process- before an action is actually dispatched, for example- then you may need to initialize the view first:

The view can also be obtained via the layout object. If you are using and have already initialized Zend_Layout, you can get at the view object much more succinctly:

This actually proxies to the ViewRenderer, and does all of the above steps for you.

Zend Framework has been designed to solve the most common problems in web application development. Web services are a big part of today's web development environment. So much so that many of our users consume our web service clients for services such as Amazon ECS, Akismet, and ReCaptcha before adopting more infrastructure-oriented components such as Zend_Registry and Zend_Log. Because web services are so important in today's web applications, we have chosen to make them 'first-class citizens' in ZF.
