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 frontEnd Web 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

What is the MVC component? • The heart of ZF web applications Best practice for application workflow CONTROLLER Design pattern that dates back to Smalltalk, circa 1979 • Model: data provider View: user interface VIEW MODEL Controller: request processor • Simple solution in most applications Sensible defaults are built in Flexible and extensible Supports advanced applications

4 ways ZF encourages best practices 1. Object-oriented • Most classes are reusable programming and extensible, allowing you to write less code 2. Testing • User-defined extensions, 3. Documentation plugins, and adapters implement interfaces and 4. Extremely simple should be well-designed classes (i.e.Widgets) • Uses many other design patterns

4 ways ZF encourages best practices 1. Object-oriented • MVC Request and programming Response can be simulated • Built-in testability for 2. Testing Controllers 3. Documentation • Extensive collection of 4. Extremely simple PHPUnit test suites serves as useful example

4 ways ZF encourages best practices 1. Object-oriented • Framework development programming process requires complete manual coverage for every 2. Testing component 3. Documentation • Framework coding standards include complete 4. Extremely simple API docblocks to support reference documentation and development tools • Examples and use cases a requirement for each component

4 ways ZF encourages best practices 1. Object-oriented • Simple interfaces are better programming for: Usability 2. Testing Extensibility 3. Documentation Testability 4. Extremely simple Maintainability • Avoid “AntiPatterns” Functional decomposition Spaghetti code http://www.antipatterns.com/

3 tools ZF offers to improve application security 1. Zend_Filter_Input • Processes values of form fields 2. Zend_Auth • Declares rules for filtering 3. Zend_View 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

3 tools ZF offers to improve application security 1. Zend_Filter_Input • Abstract interface to login credential storage 2. Zend_Auth *SBS • Provides adapters for 3. Zend_View several directory solutions LDAP File Database table others • Write your own custom directory adapters

3 tools ZF offers to improve application security 1. Zend_Filter_Input • Provides a method to format PHP objects more 2. Zend_Auth safely for HTML: 3. Zend_View *SBS <?= $this->escape($this->var); ?>

5 ways ZF helps to avoid reinventing the wheel 1. Zend_Acl • Manages application roles, resources and privileges 2. Zend_Feed • Roles and Resources may 3. Zend_Log be user-defined classes 4. Zend_Cache • Supports rule inheritance 5. Zend_Config • Supports conditional application of rules

5 ways ZF helps to avoid reinventing the wheel 1. Zend_Acl • Consume RSS feed in a single line of PHP code 2. Zend_Feed • Discover feed links 3. Zend_Log automatically 4. Zend_Cache • Imports feeds from multiple sources 5. Zend_Config • Provides feed building and posting operations

5 ways ZF helps to avoid reinventing the wheel 1. Zend_Acl • Support advanced yet easy logging operations in your 2. Zend_Feed application 3. Zend_Log • Inspired by log4j 4. Zend_Cache • Supports user-defined log formatting and writing 5. Zend_Config

5 ways ZF helps to avoid reinventing the wheel 1. Zend_Acl • Provides an interface to access persisted data 2. Zend_Feed • Supports tagging, 3. Zend_Log manipulating, iterating, and 4. Zend_Cache *SBS removing subsets • Supports multiple cache 5. Zend_Config storage backends (file, database, memcached, etc.)

5 ways ZF helps to avoid reinventing the wheel 1. Zend_Acl • Simplifies usage of configuration data for 2. Zend_Feed applications 3. Zend_Log • Provides a property-driven 4. Zend_Cache OO interface for accessing data hierarchy 5. Zend_Config • 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

MVC CURRENT APIs & WEB SERVICES Data Web Services Int. BASE Our Technology “We have created a StrikeIron API in Zend Framework because of its Web services consumption capabilities Partners: 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.” — Bob Brauer, CEO StrikeIron Web Services we include as a part of simpy del.icio.us Zend Framework: Zend Framework Technology Partnerships | 40
