Model–view–controller Model–view–controller (MVC) is a software pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user. The central component, the model, consists of application data, business rules, logic and functions. A view can be any output representation of information, such as a chart or a diagram. Multiple views of the same information are possible, such as a bar chart for management and a tabular view for accountants. The third part, the controller, accepts input and converts it to commands for the model or view. Component interactions A typical collaboration of the MVC components In addition to dividing the application into three kinds of components, the Model–view–controller (MVC) design defines the interactions between them.

I did an unconference presentation on Ajax + ZF MVC during ZendCon; there are slides and code linked to it from here: Basically, you have your XHR requests target a controller/action pair in your application, and that action then returns a response that your XHR request can use -- in whatever format your client-side code requires (XML, JSON, or HTML). -- Matthew Weier O'Phinney PHP Developer | [hidden email]Zend - The PHP Company |
Unified Modeling Language UML logo The Unified Modeling Language (UML) is a general-purpose modeling language in the field of software engineering, which is designed to provide a standard way to visualize the design of a system. It was created and developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software in the 1990s. In 1997 it was adopted by the Object Management Group (OMG), and has been managed by this organization ever since. Overview A collage of UML diagrams. The Unified Modeling Language (UML) offers a way to visualize a system's architectural blueprints in a diagram (see image), including elements such as: Although originally intended solely for object-oriented design documentation, the Unified Modeling Language (UML) has been extended to cover a larger set of design documentation (as listed above), and been found useful in many contexts.

Understanding the Zend Framework, Part 9: Adding interactivity with Ajax and JSON Introduction In Part 8 of this series, you added Yahoo!, Amazon, Twitter and Flickr results to the Chomp application. Now you're going to improve performance by loading only the data the user requests, when the user requests it. But first, let's see where we are at. How you got here This nine-part "Understanding the Zend Framework" series chronicles the building of an online feed reader, Chomp, while explaining the major aspects of using the open source PHP Zend Framework. Part 1 talked about the overall concepts of the Zend Framework, including a list of relevant classes and a general discussion of the MVC pattern. Parts 3 and 4 dealt with the actual RSS and Atom feeds. The rest of the series involves adding value to the Chomp application. Now in the final part of the series, you will use Ajax and the Zend Framework's Zend_Json component to update part of the search results page automatically with specific requested information. Back to top So what are Ajax and JSON, anyway? Listing 1. ...
Create, read, update and delete Another variation of CRUD is BREAD, an acronym for "Browse, Read, Edit, Add, Delete". DRULAB is also a variation, where "L" stands for Locking the access to the data (Delete, Read, Update, Lock, Add, Browse). This concept is mostly used in context with data protection concepts. Database applications The acronym CRUD refers to all of the major functions that are implemented in relational database applications. Each letter in the acronym can map to a standard SQL statement, HTTP method or DDS operation: Although a relational database provides a common persistence layer in software applications, numerous other persistence layers exist. User interface Create or add new entriesRead, retrieve, search, or view existing entriesUpdate or edit existing entriesDelete/deactivate existing entries Without at least these four operations, the software cannot be considered complete.

Zend Framework Dans vos scripts de vue, il est souvent nécessaire d'effectuer certaines actions complexes encore et encore : par exemple, formater une date, générer des éléments de formulaire, afficher des liens d'action. Vous pouvez utiliser des classes d'aide pour effectuer ce genre de tâches. Une aide est simplement une classe. Par exemple, nous voulons une aide nommée "foobar". Pour utiliser une aide dans votre script de vue, appelez la en utilisant $this->nomAide() . Zend_View fournit avec un jeu initial de classes d'aides, la plupart est liée à la génération d'éléments de formulaire. declareVars() : initialement prévu pour être utilisé avec strictVars() , cette aide peut être utilisée pour déclarer les variables de modèle ("template") qui sont (ou pas) déjà déclarées dans l'objet de vue, ou pour gérer des valeurs par défaut. fieldset($name, $content, $attribs) : crée un ensemble de champs XHTML . form($name, $attribs, $content) : génère un formulaire XHTML . devrait être un tableau. null , <? <? <?
Understanding the Zend Framework, Part 1: The basics The Zend Framework A couple of years ago, PHP sat at the top of the powerful-but-easy-to-use scripting languages heap — at least as far as popularity was concerned. It was installed on most UNIX®- and Linux®-based web servers. And then — suddenly, it seemed — the landscape changed. What makes the Zend Framework one of the premier frameworks used by PHP developers is that it provides clean, stable code, complete with intellectual property rights. What is the Zend Framework, exactly? Is based on PHPIs object-orientedUses the MVC paradigmHas open source contributorsHas contributors who take responsibility for the fact that their code is not the intellectual property of someone else It also aims to make your programming life easier, not just in general by instituting the MVC pattern, but also for specific things you tend to do all the time, like access databases or output to a PDF file. Zend Framework components include: Zend_Controller Zend_Db Zend_Feed Zend_Filter Zend_InputFilter Zend_Json
