Quick Start Walk Through
Zend Framework is a quot;gluequot; framework that also provides
an MVC quot;stack.quot;
Provides much flexibility but quot;best practicesquot; 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.)
quot;Use-at-willquot; architecture - if I don't like something I can
extend or replace it
Permissive open source license (modified BSD)
Doesn't hurt to have quot;The PHP Companyquot; 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
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_Service
View - 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/controller /action /key /value
Your web server's document root.
Contains the bootstrap file which all requests are routed
Contains the .htaccess file which uses mod_rewrite to make
sure all requests are rewritten to your bootstrap file.
You can use regex so that requests for static files (e.g. js,
ico, gif, jpg, png, css) are not rewritten to your bootstrap file.
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
Contains the Action Controllers for your web application.
Each of your Action Controller will extend the
Each of your Action Controller class names should end in
quot;Controller.quot; For example: FooController.
Each Action Controller can have multiple actions
represented by public functions ending in the name quot;Action.quot;
For example: barAction().
/** Zend_Controller_Action */
class IndexController extends Zend_Controller_Action
public function indexAction()
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
PUBLIC quot;-//W3C//DTD XHTML 1.0 Strict//ENquot;
<meta http-equiv=quot;Content-Typequot; content=quot;text/html;
<title>My first Zend Framework App</title>
/** Zend_Controller_Action */
class ErrorController extends Zend_Controller_Action
public function errorAction()
A place for your quot;modelquot; code.
I prefer to create a namespace in library that contains the
models specific to the web application.
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.
More controllers and actions
Some quot;Mquot; in MVC - Zend_Db is the next logical step for
most web applications
