  3. 3. Introduction <ul><li>php.MVC is a M odel V iew C ontroller (MVC) framework for PHP Web applications </li></ul><ul><li>The use of this design philosophy makes it easier for designers and programmers to focus on their respective areas of expertise </li></ul><ul><li>This design model allows Web pages or other contents (Views) to be separated from the applications business logic, or code (Model) </li></ul><ul><li>php.MVC is a PHP port of the Jakarta Struts project. </li></ul>
  4. 4. Introduction
  5. 5. The Benefits <ul><li>php.MVC is a PHP port of the Jakarta Struts project </li></ul><ul><li>Enforces modularity and application partitioning </li></ul><ul><li>Increases developer/designer role separation </li></ul><ul><li>Increases code manageability </li></ul><ul><li>Increase code extensibility (Ability to adapt to change) </li></ul>
  6. 6. The MVC Pattern Concepts <ul><li>We can see the how a typical HTTP request from a Web client (Web browser) would interact with the core framework classes and our application classes, to produce a HTTP response (Web content) to return to the Web client. </li></ul>
  7. 7. Contd.. <ul><li>To start the process, a client would send our php.MVC application a request </li></ul><ul><ul><li>perhaps a request to view a particular company sales report </li></ul></ul><ul><ul><li> </li></ul></ul>
  8. 8. Web server Directory Structure
  9. 9. MVC Libraries <ul><li>.htaccess </li></ul><ul><ul><ul><li>control who can access this directory </li></ul></ul></ul><ul><li>art directory </li></ul><ul><ul><ul><li>Is used to hold the application graphics, and will be accessible to the Web </li></ul></ul></ul><ul><li>style directory </li></ul><ul><ul><ul><li>is used to hold the application style sheets and will also be accessible to the Web </li></ul></ul></ul><ul><li>/WEB-INF directory </li></ul><ul><ul><ul><li>This is where we locate the application classes and resources. </li></ul></ul></ul>
  10. 10. Contd.. <ul><li>The tpl directory </li></ul><ul><li>holds the applications View resources, such as page </li></ul><ul><li>ModulePaths.php file </li></ul><ul><ul><li>Is used to define the application specific paths to our classes and resources </li></ul></ul><ul><li>phpmvc-config.xml file </li></ul><ul><ul><li>Is the central component of the php.MVC application. </li></ul></ul><ul><li>phpmvc-config_1_1.dtd file </li></ul><ul><ul><li>Contains the Document Type Definitions (DTD) for the phpmvc-config.xml file </li></ul></ul><ul><li>prepend.php file is used to include application files </li></ul><ul><li>Main.php file </li></ul><ul><ul><li>is the single entry point for an application, and is located in the application root directory </li></ul></ul>
  11. 11. Core component of MVC <ul><li>The XML configuration file is the &quot;switchboard&quot; of a php.MVC application. This is how we bind the various components to a HTTP request path </li></ul><ul><li>The Controller consists of the php.MVC framework classes that are responsible for routing </li></ul><ul><li>HTTP requests to the correct Form and Action classes and View resources, as defined in the application phpmvc-config.xml file. </li></ul><ul><li>The Action Form classes can be used to handle Web form checks and validation </li></ul><ul><li>The Action classes are used to access our business classes. We can direct the application flow to resources based on run-time conditions </li></ul><ul><li>The Action Dispatcher class handles the resource (template) processing </li></ul>
  12. 12. XML Application configuration system
  13. 13. Example
  14. 14. Controller <ul><li>The Controller component of the php.MVC framework consists of classes that handle a users request according to predefined configuration options </li></ul><ul><li>A typical user request may look something </li></ul><ul><ul><li>Like: </li></ul></ul><ul><li>The php.MVC Controller consists of two distinct sections: </li></ul><ul><ul><li>The Front Controller </li></ul></ul><ul><ul><li>The Controller proper </li></ul></ul>
  15. 15. Front Controller
  16. 16. The controller
  17. 17. Action Form <ul><li>An ActionForm is represented in the XML Application Configuration like this: </li></ul><ul><li>The use of an ActionForm for a particular request path is optional, and can be activated in the XML Application Configuration System using the validate attribute of the action mapping node like this </li></ul>
  18. 18. Action <ul><li>An Action class is represented in the XML Application Configuration like this: </li></ul>
  19. 19. Security <ul><li>regular expression (RE) such as &quot;^[a-z0-9]{8}$&quot; </li></ul>
  20. 20. View <ul><li>Tpl comes into view </li></ul><ul><li>Action dispatcher </li></ul>
