Zend Framework Quick Start Walk Through

Found Line

Zend Framework is a "glue" framework that also provides

an MVC "stack."

Provides much flexibility but "best practices" are still

sometimes hard to figure out (there are proposals that

address this such as Zend_Console & Zend_Build)

This presentation will focus mainly on what is suggested in Zend Framework documentation

Why We Chose Zend Framework

Clear separation between design and development (MVC)Gives a starting point for code reuse (coding standards, namespace organization, etc.)

"Use-at-will" architecture - if I don't like something I can extend or replace it

Great documentation

Permissive open source license (modified BSD)

Doesn't hurt to have "The PHP Company" behind it

Zend Framework installation

Zend_Controller quick start

Example web application on Google Code

Make sure you have PHP 5.1.4 or later (full system

requirements)

Download the latest stable release, download the latest

nightly snapshot, or use a Subversion (SVN) client to get a copy of Zend Framework

Make sure your PHP include_path contains the path to the Zend Framework library

Zend Framework contains many components that may now

be used in your web application even if you decide not to use Zend Framework MVC

Zend Framework MVC Overview

Model - many options including Zend_Db & Zend_ServiceView - Zend_View

Controller - Zend_Controller

Zend_Controller_Front uses a Front Controller pattern

Incoming requests are dispatched to Action Controllers based on the requested URL:

http://example.com

http://example.com/controller http://example.com/controller /action http://example.com/controller /action /key /value

File System Layout

Your web server's document root

Contains the bootstrap file which all requests are routed

RewriteEngine on

RewriteRule !\.(js|ico|gif|jpg|png|css)$ index.php

php_value include_path /library

php_flag register_globals off

php_value error_reporting 2047

php_flag display_errors on

html/index.php (bootstrap file)

<?php

require_once 'Zend/Controller/Front.php';

Zend_Controller_Front::run(' /application/controllers');

Contains the Action Controllers for your web application

Each of your Action Controller will extend the

Zend_Controller_Action class

Each of your Action Controller class names should end in

"Controller." For example: FooController

Each Action Controller can have multiple actions

represented by public functions ending in the name "Action." For example: barAction()

Contains the view scripts for your web application

Default extension for view scripts is phtml

Controller name is used to match the directory and action name is used to match the view script

Given FooController::barAction() the view script would be foo/bar.phtml

application/views/scripts/index/ index.phtml

application/views/scripts/error/ error.phtml

<h1>An error occurred</h1>

<p>An error occurred; please try again later.</p>

</body>

</html>

A place for your "model" code

I prefer to create a namespace in library that contains the models specific to the web application

application/views/helpers/ &

application/views/filters/

Custom view helpers and filters

Examples of Zend Framework built-in view helpers include formButton (for creating an XHTML form button), url (for creating URLs based on named routes), and htmlList (for generating unordered and ordered lists based on an array).Examples of Zend Framework built-in filters include

HtmlEntities, StringToLower, and StringTrim

Library code used by your web application

Includes Zend directory which is where Zend Framework lives I usually setup this up using svn:externals

When setting up my own libraries I like to follow the Zend Framework way of setting up namespaces

What's Next?

More controllers and actions

Some "M" in MVC - Zend_Db is the next logical step for most web applications

example web application if you want a sandbox <bradley.holt@foundline.com>
