Zend Framework Overview (Atlanta PHP May 2006)

For nearly two months, the Zend Framework has been the great talk of the PHP community. Just one day following Atlanta PHP's March meeting, the Zend Framework preview release was announced, and folks have been eager to download, play with it, and provide their feedback. At our May meeting, Ben Ramsey will take the Zend Framework for a test drive, outlining its current state, the direction it's heading, and rounding out the presentation with a quick tutorial on using the framework (code samples included). Finally, we'll start work on our group project, using the Zend Framework as a basis.

   disagreements

7. Project goals
   • Provide a repository of high quality
   components that are actively supported
   • Provide a complete system for developing web
   applications powered by PHP 5
   • Don’t change PHP -- it’s already a great
   platform (even without a framework!)

    • BSD license (was originally similar to the PHP
    license with the “advertising clause”)

11. More background
    • There is a contribution/proposal process

    License Agreement
    • There are rigid standards for writing code
    • The framework is fairly easy to use

    View Slide

15. Requirements
    • PHP 5.0.4 with PDO extensions required;
    PHP 5.1 recommended
    • Apache HTTPD server recommended for
    mod_rewrite rules, but not required
    • Download from:
    http://framework.zend.com/download

16. Set up your app structure
    • I recommend the following structure:
    /
    application/
    controllers/
    views/
    library/
    Zend/
    
    www/
    images/
    styles/
    .htaccess
    index.php
    

    View Slide

17. Server configuration
    • Create an .htaccess file with the following and
    place in www/
    php_value include_path “../library”
    RewriteEngine on
    RewriteRule !\.(js|ico|gif|jpg|png|css)$ index.php

18. Bootstrap file
    /* this file lives at www/index.php */
    include 'Zend.php';
    function __autoload($class)
    {
    Zend::loadClass($class);
    }
    $view = new Zend_View;
    $view->addScriptPath('../application/views');
    Zend::register('view', $view);
    $controller = Zend_Controller_Front::getInstance()
    ->setControllerDirectory('../application/controllers')
    ->dispatch();
    ?>

19. A “hello, world” example
    

    View Slide

20. Application structure
    • Zend Framework applications are controlled by
    instructions from the URI
    • Thus, consider the following:
    /
    /view/#
    /post/edit
    /post/save
    /post/remove/id/#
    

    View Slide

21. Create our controller
    • The framework dispatcher calls the index
    controller when someone access the root of the
    site (/), so we need to create one to handle
    these requests
    • Create IndexController.php in
    application/contorllers/
    

    View Slide

22. IndexController.php
    class IndexController extends Zend_Controller_Action
    {
    public function indexAction()
    {
    $view = Zend::registry('view');
    $view->title = 'Hiya';
    $view->body = 'Hello, World!';
    echo $view->render('hello.php');
    }
    public function noRouteAction()
    {
    $this->_redirect('/');
    }
    }
    ?>
    

    View Slide

23. Create our view
    • Create the following file (hello.php) and
    store in application/views/
    
    
    escape($this->title); ?>
    
    
    escape($this->body); ?>
    
    
    

    View Slide

24. Say “hello” to everyone
    • Now, when a user accesses http://example.org/
    or http://example.org/index, they’ll see the
    following:
    
    
    Hiya
    
    
    Hello, World!

25. What have we learned?
    • background on the framework
    • overview of components
    • quick look at the roadmap
    • how to set up your environment
    • said “hello” to the world
