Unit Test for ZF SlideShare Component

  1. 1. Copyright © 2006, Zend Technologies Inc. Introducing: Zend Framework John Coggeshall
  2. 2. Apr 11, 2014 # 2 Welcome • Today I’ll be introducing you to the Zend Framework  What it is  Why we’re doing it  How to use it  Where it’s going  How to be a part of it
  3. 3. Apr 11, 2014 # 3 Getting Started • Zend Framework is..  A modular collection of PHP classes based on PHP 5 to simplify common tasks  A starting point for your applications  A demonstration of PHP 5 best practices  A smaller component of the PHP Collaboration Project • Zend Framework isn’t…  A free-reign open source project  A religion
  4. 4. Apr 11, 2014 # 4 Goals of the Framework • Zend Framework strives to be fundamentally….  An industry-leading framework for PHP application development  A partnership between many companies already experienced in PHP Framework development • Zend Framework strives to be technically…  A source of high-quality, PHP 5 / E_STRICT compatible application components  Completely PHP 5 powered, requiring as few external PHP extensions as necessary  A minimal object hierarchy to achieve the necessary goals  Modular design allowing developers to use the framework at will, as they see fit.
  5. 5. Apr 11, 2014 # 5 Why Yet another Framework? • Keep PHP competitive with other technologies  .NET, Java, etc. • Provide “clean” IP to enable commercial use  Real companies can’t just “borrow” code from the Internet without clear licensing • “Extreme Simplicity”: It may not be simple technically, but using it should be. • Take full advantage of PHP 5
  6. 6. Apr 11, 2014 # 6 The Framework License • Zend Framework is licensed using a PHP/BSD style license  Anyone can use it, for anything, no strings attached – period. • Along with the license of the framework itself, contributors must sign a Contributor License Agreement (CLA)
  7. 7. Apr 11, 2014 # 7 There’s no such thing as a free… • Why spend so much time and effort on something, just to give it away?  Yes, we’re still interested in making money • For the continued success of PHP it must be a collaboration beyond OSS hackers  Through the PHP Collaboration project, and projects like Zend Framework, we can leverage the knowledge of some of the best in the industry in the benefit of PHP as a whole  As you might expect, Zend benefits with PHP
  8. 8. Apr 11, 2014 # 8 We eat our own dog food • Zend Framework is more than unit-tested, it is used in real-life production environments  Gives us the ability to test performance, ease of use, etc. in a practical environment  Zend and its partners are already using the preview release of the Framework to speed development of their applications  Both the Framework homepage (framework.zend.com) and our new Developer’s Zone (devzone.zend.com) use the preview release of Framework as their foundation.
  9. 9. Apr 11, 2014 # 9 The grail: Extreme Simplicity • Many of PHP 5’s most exciting new technologies are really simple to use:  Simple XML  SOAP  Tidy • While the underlying technologies may be extremely complex, the end-user APIs are reduced to an extremely simple interface
  10. 10. Apr 11, 2014 # 10 Getting the Grail • To achieve the grail of extreme simplicity  “Simple things should be simple, complex things should be possible” • Use-at-will architecture  You shouldn’t be forced into buying the whole pizza just for a slice  Use individual components (controller/model) without being forced to use everything (your own template/view) • Configuration-less  The framework should be plug-and-go, no configuration files necessary
  11. 11. Apr 11, 2014 # 11 Zend Framework from 10,000 feet
  12. 12. Apr 11, 2014 # 12 Completely PHP-5 focused • Requires PHP 5.0.4 or later for near future • Takes full advantage of the PHP exception model • Constants are all at the class-level • No functions in global namespace • ZE2 / SPL technologies fully utilized where it makes sense • Black magic __magic() functions used very sparsely
  13. 13. Apr 11, 2014 # 13 Preview Release • PR 1.2 is the latest preview release of the Framework including many immediately useful tools such as:  A basic MVC framework for application design  A PDO-based database layer  Feed (RSS, Atom) ingestion and manipulation  An HTTP client  Input data filtering  Json support for AJAX  PDF generation and manipulation  RPC / Web service support  And more!
  14. 14. Apr 11, 2014 # 14 $ svn checkout http://framework.zend.com/svn/framework/trunk • You can either get the framework preview release or check out the latest repository version • Preview Release: http://framework.zend.com/ • Repository: Getting Zend Framework
  15. 15. Apr 11, 2014 # 15 Installing Zend Framework • Installing the framework is very easy, just modify your include_path to include the library/ directory From php.ini: From .htaccess …… include_path=“.:/usr/local/lib/php:/usr/local/lib/ZendFramework” …… …… php_value include_path “.:/usr/local/lib/php:/usr/local/lib/ZendFramework” ……
  16. 16. Apr 11, 2014 # 16 MVC Pattern • MVC, or Model View Controller pattern is a powerful technique for developing user interfaces • Originally was conceived for client-side GUI applications and adopted to the web • Zend Framework provides a simplistic MVC model
  17. 17. Apr 11, 2014 # 17 Example Controller • Note: indexAction() is declared abstract in Zend_Controller_Action, and therefore must be defined in any Action/Page controller
  18. 18. Apr 11, 2014 # 18 Passing Parameters • Beyond $_GET/$_POST you can also pass parameters to a specific controller action by appending them to the URL:  http://localhost/foo/dosomething/param1/value1/param2/value2 • Parameters can be accessed from within the action by name  $this->_getParam(<key> [, <default value>]);  $this->_getAllParams();
  19. 19. Apr 11, 2014 # 19 Dealing with 404s • 404 errors are no longer the responsibility of Apache per-se, and are more likely to result in a ‘Class not found’ / ‘Method not found’ exception • To deal with these Zend Framework provides two methods  In the event of a controller not found, the IndexController::noRoute() method will be called instead  In the event a controller action is not defined, it is the responsibility of the controller to implement safeguards (i.e. __call() which traps bad action calls)
  20. 20. Apr 11, 2014 # 20 Chaining Controllers • Controllers can be chained together to either break business logic out into components, or to otherwise redirect the user  $this->_forward(<controller_name> [, <parameters>])  Parameters are a series of key/value pairs  Controller Chaining does not occur until the current action is complete, to immediately forward you must return from the current action after calling _forward() • Forwarding does not cause a refresh on the client, to physically refresh the browser  $this->_redirect(<url>);
  21. 21. Apr 11, 2014 # 21 Final thoughts on MVC • Although the pattern dictates three individual class types, they are as conceptual as functional • For instance a “model” or “view” isn’t absolutely necessary to gain most of the benefit of MVC  You can always perform queries from a controller  You can always print output from a controller • Although not necessary, they are never the less recommended
  22. 22. Copyright © 2006, Zend Technologies Inc. Input Filtering
  23. 23. Apr 11, 2014 # 23 Zend_InputFilter • Security is a primary concern in Zend Framework • As such, we provide facilities to clean and manage untrusted data in your applications via Zend_InputFilter and Zend_Filter  Provides a number of methods for filtering data against many common data types (digits, alphanumeric, alpha, phone, etc.)
  24. 24. Apr 11, 2014 # 24 Using Zend_InputFilter • With Input Filter you can both test data types and retrieve filtered data easily • Note, by default the source of the data and all of it’s references are destroyed when filtered
  25. 25. Apr 11, 2014 # 25 Zend_Mail • Simplifies building and sending e-mail • Supports MIME types and multipart e-mail • Supports multiple transports and persistent connections automatically • Supports large file attachments via the streams API improving performance
  26. 26. Apr 11, 2014 # 26 Sending HTML mail is now really easy
  27. 27. Apr 11, 2014 # 27 Zend_Search • PHP 5 implementation of the popular Lucene search engine from the Java world. • Simplified API • Requires no special PHP extensions • Fully compatible with the binary index format of Java Lucene 1.4 and above
  28. 28. Apr 11, 2014 # 28 Zend_Search Features • Ranked Searching  Best results always first • Many Query types: phrase, wildcard, proximity • Search by field (Author, title, body, etc.) • Robust, and simple API  One-method intelligent searches against indexes, or complex OO queries if desired  Index multiple document types, with different field requirements
  29. 29. Apr 11, 2014 # 29 Using Zend_Search • Using Zend Search is very easy • The search engine also boasts a parser for google-like searching: zend php -java
  30. 30. Apr 11, 2014 # 30 Adding documents to the index
  31. 31. Apr 11, 2014 # 31 Cool things about Zend_Search • The Lucene search engine allows you to index multiple document types in a single index, each with different index fields  Index Individual documents with different searchable criterion  I.e. Index code samples by functions used, while articles by title, author, and keywords in the same index • Because it is 100% compatible with Lucene 1.4+, it is compatible with all pre-created index files
