CakePHP 2.0 - PHP Matsuri 2011
- 1. CakePHP 新バージョン 2.0
- 2. Graham Weldon • PHP developer 11 years • CakePHP core contributor 4 years • Visiting Japan for 3 years
- 3. CandyCane http://my.candycane.jp • Recently helping with CandyCane • Project managed by Ando • Lots of good fixes and updates made recently • Good fun working with Japanese developers • Check it out!
- 4. Learning Japanese • I am learning Japanese • You can speak “very basic” Japanese with me • But I will have lots of problems understanding • Please forgive me for any mistakes • I can write Japanese better than I can speak it :-)
- 5. CakeFest Conference • Manchester, UK • 4 days! • ~100 attendees • People from many countries • Lots of learning • Lots of drinking
- 6. Overview
- 7. Major Points • No more PHP4 • Refactored throughout • New Features • Faster • New Conventions
- 8. PHP5 • 5.2.6+ (Including 5.3) • Exceptions • PDO Datasources • SPL • Filters • Support for anonymous functions
- 9. Upgrade Console • Make upgrading simpler • Do all the tedious work for you • Automate as much as possible • Its not perfect
- 10. Conventions
- 11. File Naming • MyClass => my_class.php
- 12. File Naming • MyClass => my_class.php
- 13. File Naming • MyClass => my_class.php • MyClass => MyClass.php • CamelCased Directories • “Namespace-ish” separation • Preparing for PHP 5.3 and PSR-0
- 14. File Naming • Singular directory names • Model/Behavior/MyBehavior.php • View/Helper/MyHelper.php
- 15. Moved App* Classes • Model/AppModel.php • Controller/AppController.php
- 16. New Class Loader • Goodbye to App::import() • Say Hello to App::uses() • Similar functionality • Looks like PHP 5.3 use keyword
- 18. App::uses Example App::uses( ClassName, Package/SubPackage );
- 19. App::uses Example App::uses( ClassName, Package/SubPackage );
- 20. App::uses Example App::uses( ClassName, Package/SubPackage );
- 21. Configuring Packages • Use App::build() to define where packages are located • Defaults to app/Lib • Core provides defaults
- 22. App::build() • App::PREPEND • App::APPEND • Control your insertion order • Greater flexibility
- 23. Exceptions and Errors
- 24. cakeError() • No more cakeError() • Replaced • Exceptions • Exception Handlers • Much better!
- 25. Benefits • Extensible error handling • Common sense default exceptions • Configurable handling • PHP 5.3 awesomeness (if you want)
- 26. Custom Rendering
- 27. PHP 5.3?
- 28. We’re web developers • HTTP Exceptions • Named as you would expect • CakeException for development errors • Shows as Error 500 in production
- 29. HTTP Exceptions • All the common HTTP Errors are built in • Renderer handles display and output
- 30. Example
- 32. I18n Shortcut • Simpler • Returns by default • Automatic sprintf() functionality
- 33. Return by default • CakePHP 1.x
- 34. Return by default • CakePHP 1.x • CakePHP 2+
- 35. sprintf() built in • CakePHP 1.x
- 36. sprintf() built in • CakePHP 1.x • CakePHP 2+
- 37. Collections
- 38. CakePHP 1.x • Previously all extensions worked differently • Helpers • Behaviors • Components • Tasks • No common interface / API
- 39. CakePHP 2.x • Collection objects to manage them • HelperCollection, TaskCollection, BehaviorCollection, ComponentCollection • Similar functionality, same API • Easy to use and extend
- 40. Responsibilities • Load objects when required • Unload objects • Alias objects • Manage callbacks
- 41. Object Loading • $this->Html now available • The same API exists for other collections: • Behaviors • Components • Tasks
- 42. Aliasing • Handy for providing custom functionality • Used to be annoying to “override” defaults • Possible, but not an elegant solution
- 43. CakePHP 1.x
- 44. CakePHP 2.x
- 45. Global usage • Once an alias is defined, its used everywhere • Anything else accessing $this->Auth would use CustomAuthComponent
- 46. More control with Collections • Unload • Disable • Enable
- 47. Console
- 48. Console Changes • Console now has a home • app/Console • Coloured output • Better input handling • Generated help • Various output formats
- 49. Colour • Simple markup to colourise your output • Warning • Error • Info • Question • ... and more
- 50. Simple markup
- 51. Colour
- 52. Auto-Generated Help • Writing documentation sucks • Using the ConsoleOptionParser gives you help for free • Simple to use • Two birds with one stone
- 54. Request & Response
- 55. CakeRequest • All request information in a single place • Use $this->request everywhere • Memory use is lower • No more copies of copies of copies of arrays all over the place • Backwards compatible interface
- 56. CakeResponse • Again, consolidate logic to a single location • Use $this->response everywhere • Backwards compatibility provided
- 57. Sessions
- 58. Sessions • Remove duplicated code (DRY) • Shouldn’t be always included (1.3 fix) • Modelise data handling • Access anywhere • Allow simple customisation • Separate Caching, Database, etc.
- 59. Sessions SessionHandler Database Cache PHP
- 60. Sessions SessionHandler Database Cache PHP
- 61. Sessions SessionHandler Database Cache PHP My Custom Engine
- 62. Sessions SessionHandler Database Cache PHP Cake Session My Custom Engine Handler Interface
- 64. AuthComponent AuthComponent Authentication Authorization
- 65. AuthComponent • No more magic logins • No more magic hashing • Easier to understand the workflow • Easier to extend • Easier to modify
- 66. Authentication • Form • HTTP Basic • HTTP Digest • Custom
- 67. Authorization • Controller • Action (ACL) • CRUD (ACL) • Custom
- 68. Example Login
- 69. Email
- 70. EmailComponent • No longer a component • Set of separate classes • Easily used from Models and Consoles • Component is deprecated
- 71. Email Example
- 72. Email Example In Models!
- 73. Unit Testing
- 74. Unit Testing • PHPUnit is the de-facto standard for PHP • SimpleTest has less features • SimpleTest was not PHP5 ready when we started • PHPUnit offers greater features • More flexibility in testing
- 75. Performance
- 76. Performance • All round increases in performance • Lazy Loading • New Conventions => Less Inflector • Simpler dispatch • Persistent DBO cache

- #4: - I have recently been contributing to the CandyCane project\n- Its a great opportunity to work with japanese developers\n
- #5: - I am learning japanese\n- People can try and talk to me in Japanese\n- I will probably have too much trouble understanding\n- Best to stick to English\n- I can write Japanese better than I can speak Japanese\n

- #32: \n
- #33: - Ask who in the audience has worked on a moderate sized application with translation capabilities\n- Mention how messy code can get when you have lots of shortcut usage in view files\n
- #34: - We have made the “double underscore” shortcut function return the result by default\n- Previously it would echo out the result, unless you supplied “true” as the second parameter\n- This makes __() usage shorter\n
- #35: \n
- #36: - If you wanted to inject values into a tranlated string, you need to use sprintf()\n- This lets you provide a translatable string, without hard coding data that changes\n- We now provide sprintf functionality inside the “double underscore” shortcut function\n- Makes code easier to read and maintain\n

- #41: \n
- #42: \n
- #43: \n
- #44: - If you wanted to provide a custom Authentication component\n- You have to hack in the “Auth” variable on the controller instance\n- Not very flexible\n
- #45: - CakePHP 2 allows you to “alias” an object.\n- Here we use the “CustomAuthComponent” with the instance variable name “Auth”\n- Just defined the className for Auth at the Controller level\n

- #51: \n
- #52: - Example output\n
- #53: - Writing documentation can be a tedious job\n- The option parser can generate console help for users\n
- #54: \n
- #55: \n
- #56: - Copying arrays uses a lot of memory if its done a large number of times\n- We’re referencing an object instead of duplicating arrays\n- Yields memory consumption benefits\n

- #65: \n
- #66: - Was very tightly coupled\n- Separate adapters now\n- Easier to modify and extend\n
- #67: \n
- #68: - Built in Authentication mechanisms\n
- #69: \n
- #70: - Need to do login checking within the app\n- Its a couple of extra lines\n- Not too bad, given how easy it is to customise now\n
