There is also another view object to create CSV output. The Controller is implemented as a series of controller scriptsone for each Transaction Patternwhich are activated by a component script.

PHP Software Architecture Part 1: MVC

Unlike some implementations which require a separate controller for each transaction, each of my controllers is for a class or php model view controller of transaction, so the same controller script can be shared by all transactions of the same class. Each of these scripts deals with the following: It instantiates an object for each business entity identified by the component script.

  • MVC in PHP

It calls methods on those objects as appropriate. Most will perform some sort of communication with the database although some may not. Data is passed into and out of these objects as standard PHP arrays.

Principles Of MVC for PHP Developers

In this way an object can deal php model view controller any number of database occurrences both as input or output. Note that my implementation of MVC differs from the Java implementation in the following ways: Controllers do not select which View to use.

Each of my page controllers is tied to a single view as described in Transaction Patterns for Web Applications. There is, in effect, a separate Transaction Pattern for each type of use case.

Principles Of MVC for PHP Developers

The Model does not send updates to php model view controller View. When the Model has finished the actions requested by the Controller, the Controller will instantiate its one and only View, inject the Model s into the View, and the View will then extract all data from the Model s php model view controller render it in the desired format.

The View does not send user gestures to the Controller. Communication is always one way from the Controller to the View, never from the View to the Controller.

With web applications there are only two possible actions - GET and POST - and these are received by the Controller which then calls the appropriate method s on the Model s followed by a single call to the View. Figure 2a shows a slightly?

As I said in the introductionmy implementation of MVC is combined with the 3-Tier Architecture which has separate layers for Php model view controller logic, Business logic and Data Access logic.

How the two php model view controller interact is shown in Figure 3a: Figure 3a - The MVC and 3-Tier architectures combined This implementation has very high Levels of Reusability due to the number of components which are either pre-written and come supplied with the framework, or are generated by the framework.

Controller Component This component is comprised of the following: A separate and unique Component script for each user transaction. Each of these is generated from the Data Dictionary.

The Model-View-Controller (MVC) Design Pattern for PHP

A sharable Controller script which is supplied in the framework in the catalog of Transaction Patterns. View Component The Model is never supposed to handle the output php model view controller its data to any particular device or medium.

Instead it is supposed to transfer its data to another object which deals with that device or medium. The HTML component operates as follows: It is the only part of the pattern the user should be interacting with.

The Controller can be summed up simply as a collector of information, which then passes it on to the Model to php model view controller organized for storage, and does not contain any logic other than that needed to collect the input. The Controller is also only connected to a single View and to a single Model, making it a one way data flow system, with handshakes and signoffs at each point of data exchange.
