Ch-ch-anges C a k e P H P 2 . 0

CakePHP 2.0No more PHP4, PHP 5.2.6+Many re-factored/re-built internal & externalAPI’sNew features!Faster!Updated conventions.

PHP5Use native features: Exceptions. Filter ext. PDO. SPL. json_encode()

Conventions

Updated conventions ClassName = FileName.php View/Helper/HtmlHelper.php => HtmlHelper. CamelCased directories. Preparing for PHP5.3 and PSR-0

New loaderApp::import() - Old and busted.App::uses() - New hawtness.

Examples

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’);

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’); Classname

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’); Classname Package

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’); Classname Package App::uses(‘CakeEmail’, ‘Network/Email’);

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’); Classname Package App::uses(‘CakeEmail’, ‘Network/Email’); Classname

ExamplesApp::uses(‘AuthComponent’, ‘Controller/Component’); Classname Package App::uses(‘CakeEmail’, ‘Network/Email’); Classname Package

PackagesUse App::build() to deﬁne paths where anypackage lives.Sensible defaults come built in.Undeﬁned packages default to checkingapp/Lib

pathsUse App::build() to deﬁne paths wherepackages can be found.Can use App::PREPEND and App::APPENDto control insertion order.

Bad things happen

ExceptionsObject::cakeError() is dead.New Exceptions & Exception handlingreplace it.More extensible and conﬁgurable handling.

Example 1 <?php 2 // Customize the renderer. 3 Configure::write(Exception, array( 4 handler => ErrorHandler::handleException, 5 renderer => MyCustomExceptionRenderer, 6 log => true 7 )); 8 9 // Replace everything.10 Configure::write(Exception, array(11 handler => function ($e) {12 echo Oh noes;13 }14 ));

Built-in exceptionsAll previous Object::cakeError() areexceptions.Improved testing.Suite of HTTP exceptions. Great for errorpages.CakeException for development errors.Treated as 500 errors in production.

HTTP ExceptionsMost common HTTP exceptions are built in.The names are what you would expect.Conﬁgured Exception handler will get theexceptions and render an error page.

HttpExceptions1 <?php2 public function view($id = null) {3 $this->Tag->id = $id;4 if (!$this->Tag->exists()) {5 throw new NotFoundException(__(Invalid tag));6 }7 $this->set(tag, $this->Tag->read(null, $id));8 }

Error Configuration Conﬁgure used for error/exception settings. Sensible defaults. Uses Debugger in development Logs errors in production. You can change out the whole thing.

i18nNo more true.Automatic sprintf()

Examples__(‘Some string’)Always returns.__(‘Some %s’, $value);Does what you want it to.

Unify disparate apis

Unify & syngergizeHelper, Components, Behaviors & Tasks.Similar, but interacting with each was slightlydifferent.Collection objects unify all of them. HelperCollection, ComponentCollection, TaskCollection, BehaviorCollection

CollectionsLoad objects at runtime.Unload objects.Alias objects.Trigger callbacks.

Loading$Html = $this->Helpers->load(‘Html’, $settings);$this->Html works from that pointforward.The same API exists for components, tasks,behaviors.

Aliasing1 <?php2 public $helpers = array(3 Html => array(4 className => MyHtmlHelper5 )6 );

AliasingOnce an alias is created, that alias is usedeverywhere.With the above controller code, all otherHelpers would use MyHtmlHelper for$this->Html.

Unload and disable$this->Components->disable(‘Auth’);$this->Components->enable(‘Auth’);$this->Components->unload(‘Auth’);

Callbacks$this->Helpers->trigger(‘beforeRender’, array(&$this));Fires method on all enabled objects.Implement custom hooks in base classes.

Console

Console improvementsColoured output & output levels.Less coupled & easier to test.Better input handling.Generated help.XML help. Good for integration with othertools.

COLORZSimple formatting to add styles to output.$this->out(‘<warning>Uh oh</warning>’);$this->out(‘<error>Kaboom</error>’);$this->out(‘<info>Hi</info>’, 1, Shell::VERBOSE);

Input handlingMore unix-y input handling.Long and short options.Validated options.Boolean options.Required arguments.

Generated helpDeﬁning command structure withConsoleOptionParser means you get help forfree.--help and -h supported by all shells.--help xml generates xml help.

Request &Response

CakeRequestConsolidates request interrogation logic.$this->request everywhere.Lower memory use by not copying arrayseverywhere.Backwards compatible read only interfacestill around.

CakeResponseConsolidates response generation.$this->response everywhere.Deprecated methods still around.Controllers can return response objects.

example1 <?php2 class PostsController extends AppController {3 public function simple() {4 return new CakeResponse(array(5 body => Simple response6 ));7 }8 }

Sessions

SessionsSessions were tough in the past.Custom session handlers weren’t on the sameﬁeld as core ones.

SessionsCore, App, and Plugin session handlers allwork the same.CakeSessionInterface interface has to beimplemented.Same built-in options exist.

Using built-ins 1 <?php 2 Configure::write(Session, array( 3 defaults => php 4 )); 5 Configure::write(Session, array( 6 defaults => database 7 )); 8 Configure::write(Session, array( 9 defaults => cache,10 handler => array(11 config => session12 )13 ));

Using an app/plugin 1 <?php 2 Configure::write(Session, array( 3 defaults => database, 4 handler => array( 5 engine => Custom 6 ) 7 )); 8 Configure::write(Session, array( 9 defaults => php, 10 handler => array( 11 engine => Plugin.SessionHandler 12 ), 13 ini => array( 14 session.cookie_httponly => true 15 ) 16 ));

Authorization

AuthComponentSplit into authorization and authenticationadapters.Easier to modify and extend.No magic logins.No magic hashing of passwords.

Built-insAuthentication Authorization Form. Controller. HTTP Basic. Actions (Acl) HTTP Digest. CRUD (Acl) custom custom

Logging in 1 <?php 2 class UsersController extends AppController { 3 public function login() { 4 if ($this->request->is(post)) { 5 if ($this->Auth->login()) { 6 $this->Session->setFlash(Welcome back!); 7 $this->redirect($this->Auth->redirect()); 8 } else { 9 $this->Session->setFlash(Login credentials were invalid.);10 }11 }12 }13 }

Auth ConfigurationWay less, because there is less magic.Easier for beginners to grok.Easier for veterans to customize.

EmailDecomposed into several classes.Email is easily accessible from models &shells.EmailComponent is deprecated, because itdoesn’t really add anything at this point.

Simple Example1 <?php2 App::uses(CakeEmail, Network/Email);3 $mail = new CakeEmail();4 $mail->from(mark.story@gmail.com, Mark Story)5 ->to(steve@apple.com, Steve Jobs)6 ->subject(Love the new imacs)7 ->send(I <3 you so much.);

Templates 1 <?php 2 App::uses(CakeEmail, Network/Email); 3 $mail = new CakeEmail(); 4 $mail->from(mark.story@gmail.com, Mark Story) 5 ->to(steve@apple.com, Steve Jobs) 6 ->subject(Love the new imacs) 7 ->template(love_you, simple) 8 ->emailFormat(html) 9 ->viewVars($vars)10 ->send();

Mail TransportsExtracted out as separate classes.3 built-in transports, and you can make yourown.

Testing

TestingPHPUnit is the de-facto standard.SimpleTest is less feature rich, and didn’thave a PHP5 compatible version when westarted.Tune in for my talk on PHPUnit.

Performance

All winLazy loading everywhere it made sense. Components, helpers, associated models.Removed most getInstance() methods.New conventions mean less Inﬂector calls.Streamlined dispatch cycle.Persistent dbo cache.
