ZEND FRAMEWORK ADVANTAGES

• Best Practices—As an exemplar ZF is best practice.

• Productive—reuse code quickly and often.

• Simple & Easy—just like PHP, ZF is easy to adopt.

• Extensible & Flexible—customize & add your value.

• High Quality—rigorously tested + built-in tests to use.

• Friendly License—new BSD = reuse code however you like; Apache-like CLA = safety for corporations.

10 Things Every Developer Should Know about Zend Framework

1. Use-at-will architecture2. Enterprise level development framework3. Object Oriented, and not ashamed of it4. Web Services are first-class citizens5. It’s backed by Zend as well as Community6. Ajax is not an afterthought7. Only pure PHP implementation of Lucene8. A huge community that is just an email away9. Identity 2.010. Documentation up the wazoo ☺☺☺☺

And just in case you forget one of those. . .

• Hosting will not be a problem



I5/OS Power Platform Specifics

• Zend Framework works the same

• Brings the world of MVC to the RPG community

• Can use with i5 Toolkit and 5250 API, etc.

• PDO for DB2 in beta (See 1.6 RC2) in 1.7

� can use PHP/i5 TOOLKIT instead to DB2

� PDO DB2 adapter preview version available.

• Use PACE Apache port 8000, .htacess critical to ZF

SELECTED ZEND FRAMEWORK USERS


i5 Specific Example – Beverage Distributor

• #1 Wine and Spirits wholesaler in NJ

• Application – Web based customer care system.

• Problem – Originally a .NET app that was middleware between backend DB2 and frontEndWeb app.

� Issues with Syncing between FE and BE, data mismatches

� Finger pointing when problems, different owners at each layer

� Hard to extend and no onsite expertise


MODEL-VIEW-CONTROLLER

DESIGN PATTERN

What is the MVC component?

• The heart of ZF web applications

� Best practice for application workflow

� Design pattern that dates back to

Smalltalk, circa 1979

• Model: data providerView: user interfaceController: request processor

• Simple solution in most applications

� Sensible defaults are built in

� Flexible and extensible

� Supports advanced applications

ZF= Developer Best Practices

4 ways ZF encourages best practices

1. Object-oriented programming

2. Testing3. Documentation

4. Extremely simple

• Most classes are reusable and extensible, allowing you to write less code

• User-defined extensions, plugins, and adapters implement interfaces and should be well-designed classes (i.e.Widgets)

• Uses many other design patterns




4. Extremely simple

• MVC Request and Response can be simulated

• Built-in testability for Controllers

• Extensive collection of PHPUnit test suites serves as useful example




4. Extremely simple

• Framework development process requires complete manual coverage for every component

• Framework coding standards include complete API docblocks to support reference documentation and development tools

• Examples and use cases a requirement for each component




4. Extremely simple

• Simple interfaces are better for:

� Usability

� Extensibility

� Testability

� Maintainability

• Avoid “AntiPatterns”� Functional decomposition

� Spaghetti code

� http://www.antipatterns.com/

3 tools ZF offers to improve application security

1. Zend_Filter_Input2. Zend_Auth3. Zend_View

• Processes values of form fields

• Declares rules for filtering and validating input data

• Serves as a “cage” for data; only valid data come out

• Provides method for escaping values, to make them safer for HTML output



• Abstract interface to login credential storage

• Provides adapters for several directory solutions

� LDAP

� File

� Database table

� others

• Write your own custom directory adapters

*SBS



• Provides a method to format PHP objects more safely for HTML:

<?= $this->escape($this->var); ?>

*SBS

5 ways ZF helps to avoid reinventing the wheel

1. Zend_Acl2. Zend_Feed3. Zend_Log4. Zend_Cache5. Zend_Config

• Manages application roles, resources and privileges

• Roles and Resources may be user-defined classes

• Supports rule inheritance

• Supports conditional application of rules



• Consume RSS feed in a single line of PHP code

• Discover feed links automatically

• Imports feeds from multiple sources

• Provides feed building and posting operations



• Support advanced yet easy logging operations in your application

• Inspired by log4j

• Supports user-defined log formatting and writing



• Provides an interface to access persisted data

• Supports tagging, manipulating, iterating, and removing subsets

• Supports multiple cache storage backends(file, database, memcached, etc.)

*SBS



• Simplifies usage of configuration data for applications

• Provides a property-driven OO interface for accessing data hierarchy

• Supports multiple storage formats (.INI files, XML)

• Supports inheritance of configuration sections

• Optional; Zend Framework is configuration-less

A SOAP SERVER

• Zend_Soap_Server class is intended to simplify Web Services server part development.

• It’s OO wrapper around SOAP PHP extension SoapServer class which gives a flexible way to operate SOAP Server object.

• Two operational modes: WSDL and non-WSDL.

SOAP – Server example

SOAP - Client

• Zend_Soap_Client class is intended to simplify Web Services client part development.

• Two operational modes: WSDL and non-WSDL.

• Base for specific clients development (e.g. Zend_Soap_Client_DotNet is under development now).

SOAP Client - Example

CURRENT APIs & WEB SERVICES

“We have created a StrikeIron API in Zend Framework

because of its Web services consumption capabilities

and the momentum it is experiencing as a platform for

developing Web applications. This makes it extremely

easy for PHP developers to access multiple StrikeIron

services in a consistent way, greatly extending the

capabilities of Web apps that utilize Zend Framework.”
