Zend Framework background

What is the Zend Framework?

• “Zend Framework is a high quality and open source framework for developing Web Applications and Web Services.”

• Zend’s answer to Enterprise-grade frameworks

• Zend’s tool to promote PHP use in the Enterprise

What is the Zend Framework?

• Like PEAR, it is a collection of classes that may be used together or separately

• Designed to be free from Intellectual Property disagreements

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!)

Project goals

• Embrace collaboration and community to further advance PHP 5 programming

• Positively contribute to the PHP 5 ecosystem and the PHP Collaboration Project

PHP Collaboration Project

• a solid framework/development environment

• enriched development tools (Eclipse)

• best practices

Zend Framework License

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

• Located here: http://framework.zend.com/license/

More background

• There is a contribution/proposal process

• All contributors must sign the Contributor License Agreement

• There are rigid standards for writing code

• The framework is fairly easy to use

• Stable release by Fall 2006?

Setting up your environment

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

Set up your app structure• I recommend the following structure:/

application/

controllers/

views/

library/

Zend/

www/ images/

styles/

.htaccess

index.php

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

Bootstrap file<?php

/* 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();

?>

A “hello, world” example

Application structure• Zend Framework applications are controlled by

instructions from the URI

• Thus, consider the following:

/

/view/#

/post/edit

/post/save

/post/remove/id/#

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/

IndexController.php<?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('/');

}

}

?>

Create our view• Create the following file (hello.php) and

store in application/views/

<html>

<head>

<title><?php echo $this->escape($this->title); ?></title>

</head>

<body>

<?php echo $this->escape($this->body); ?>

</body>

</html>

Say “hello” to everyone• Now, when a user accesses http://example.org/

or http://example.org/index, they’ll see the following:<html>

<head>

<title>Hiya</title>

</head>

<body>

Hello, World!

</body>

</html>
