Zend Framework & MVC Introduction - Zend Framework Quick Start
Zend Framework Zend Framework is an open source, object oriented web application framework for PHP 5. Zend Framework is often called a 'component library', because it has many loosely coupled components that you can use more or less independently. Using these components, we will build a simple database-driven guest book application within minutes. Model-View-Controller So what exactly is this MVC pattern everyone keeps talking about, and why should you care? Note: More Information Let's break down the pattern and take a look at the individual pieces: Model - This is the part of your application that defines its basic functionality behind a set of abstractions.

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.[1][2] 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.[3] Component interactions[edit] 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.[4] Use in web applications[edit] History[edit] See also[edit]

Welcome to the Doctrine Project — Doctrine-Project 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.[1] It was created and developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software in the 1990s.[2] In 1997 it was adopted by the Object Management Group (OMG), and has been managed by this organization ever since. Overview[edit] 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:[4] 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),[5] and been found useful in many contexts.[6] History[edit] History of object-oriented methods and notation.

How to Write a Batch File (with Examples) Note: In Linux, shell scripts are used instead of batch files.

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[edit] 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[edit] 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 , <? <? <?

ECMAScript 5 Strict Mode, JSON, and More Previously I analyzed ECMAScript 5’s Object and Property system. This is a huge new aspect of the language and deserved its special consideration. There are a number of other new features and APIs that need attention, as well. The largest of which are Strict Mode and native JSON support. Strict Mode Strict Mode is a new feature in ECMAScript 5 that allows you to place a program, or a function, in a “strict” operating context. Since ECMAScript 5 is backwards-compatible with ECMAScript 3, all of the “features” that were in ECMAScript 3 that were “deprecated” are just disabled (or throw errors) in strict mode, instead. Strict mode helps out in a couple ways: It catches some common coding bloopers, throwing exceptions.It prevents, or throws errors, when relatively “unsafe” actions are taken (such as gaining access to the global object).It disables features that are confusing or poorly thought out. Most of the information about strict mode can be found in the ES5 specification [PDF] on page #235.

Zend Framework Zend Framework inclue plusieurs aides d'action par défaut : AutoComplete pour des réponses automatiques à des auto-complétions AJAX ; ContextSwitch et AjaxContext pour distribuer des formats de réponse alternatifs pour vos actions ; FlashMessenger pour gérer des messages entre les sessions ; Json pour encoder et envoyer des réponses JSON ; Redirector, qui fournit différentes implémentations pour rediriger vers des pages internes ou externes à votre application ; et ViewRenderer pour automatiser le processus de paramétrage de vos objets de vues dans votre contrôleur et du rendu de ces vues. AutoComplete Beaucoup de librairies javascript AJAX propose une fonctionnalité dite d'auto-complétion. Une liste de résultats possibles est chargée au fur et à mesure que l'utilisateur saisit. L'aide AutoComplete est destinée à simplifier le retour de ces valeurs vers la librairie Javascript. L'utilisation basique ressemble à ceci : Par défaut, l'auto-complétion : Les méthodes disponibles sont : <? JSON.
