The document summarizes plans for CakePHP 2.0, including: - Refactoring the core code and removing unused code. - Dropping support for PHP 4 and supporting PHP 5.2.6 and above. - Replacing the SimpleTest unit testing framework with PHPUnit. - Standardizing how objects inherit through components. - Removing duplicated code and relying more on PHP's Standard PHP Library. - Centralizing request and response handling. - Allowing custom session handlers through an interface. - Lazy loading nested objects to optimize performance.

No more group tests
But theres a PHP Unit way to achieve this

73. Collections
Organising

74. Collections

75. Components

76. Components

77. Components

78. Components
What does this mean in the scheme of

83. SPL
Replacing what we can

84. SPL
Standard PHP Library
Provides awesome File and Folder
operations
Classes handy for a whole range of things
No need to re-implement in the core
CakePHP 1.x was ahead of its time
PHP has caught up
Time to cut the fat

85. Non-SPL
Again, don’t reinvent the wheel
Removing duplicate code like JSON
encoding
Can now rely on this functionality shipping
with PHP

86. Exceptions

87. Exceptions
Using exceptions to indicate errors in the
core
Easier to control
More “OO”
Removing cakeError

88. Request
Response
Refactoring, centralising.

89. Request / Response
Request represents an incoming request
It replaces functionality through Controller,
Dispatcher, RequestHandler and $this-
>params everywhere
ArrayAccess implementation for backwards
compatibility

90. Request / Response
Protect users form themselves
Protect developers from users
Protect developers from stupidity
Encapsulate both the request and response
in order to provide a central location to
handle requests and responses, but retain
flexibility

91. Sessions

92. 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.
