What I'm Going To Talk AboutWhat I'm Going To Talk About

●Yii2● PHP 5.5

(Not really related with Yii2, just filling some time for the Iftar)

Let's talk about Yii firstLet's talk about Yii first

● A macro PHP framework● A lot of functionalities● Great design● Easy to extend● Easy to configure

● But hard learning-curve

Yii FeaturesYii Features

● MVC● DAO, Active Record, Database Migration● Authentication/Authorization● Skinning/Theming● Web Services● I18n, L10N● Cache● And many more

Yii2Yii2

● Yii2 is now in public preview.– It's not even alpha– Don't use it for production– Not all functionalities from Yii1.1 has been

imported.

● Supports PHP5.3+● Most of the changes are in redesigning the

architecture.

What's new in What's new in Yii2?Yii2?

NamespaceNamespace

● Actually Yii1.1 has support namespace usage in user's code (since 1.1.5) using autoloading

● For PHP5.3+ usage only (Yii1.1 still supports PHP5.2)

● Support PSR-0

Better IDE support

Can easily be mistaken with other Strings

NamespaceNamespace

● Yii1.1 classes has to be in global namespaces

● To prevent conflict, allclasses in Yii1.1 use 'C' prefix.

Namespace in Yii2Namespace in Yii2

● Better namespace organization– e.g. we used to have–

–

–

–

– No more longclass name

Components and ObjectComponents and Object

● In Yii1.1, we have CComponents– Getter/Setter through magic __get, __set, __call– Behavior– Event.

● In Yii2 we have Object and Component– Object, basic data structure, getter/setter,

toArray, object configuration, className (added in PHP5.5).

– Component, extends Object, added event and behavior

Object ConfigurationObject Configuration

● In Yii1.1●

●

●

● In Yii2

Event HandlerEvent Handler

● More straightforward using jQuery-like event handler

View ObjectView Object

● In Yii1.1 'view' is implemented as plain php file.

View ObjectView Object

● In Yii2, the view is implemented as a View object

View ObjectView Object

● Controller and Widget now accessed as View's context

● Easily do view-rendering every where, not just in controller

● CClientScript responsibility is now part of View object.

● Fragment cache moved from Controller to View object

● Supports multiple non-native renderer like Smarty and Twig

ModelsModels

● Yii2 introduces formName– Yii1.1 uses hardcoded class name

ModelsModels

ModelModel

● Easy loading (mass attribute assignment from $_POST or $_GET)

ModelModel

● Mass object assignment, e.g. Tabular Input

WidgetsWidgets

● In Yii1.1, Widget helps a lot. But declaring one can give great pain.

● Bad IDE support

WidgetsWidgets

● In Yii2, added className() method (PHP5.3) and begin(), end() method.

Query BuilderQuery Builder

● Query builder stands alone

ActiveRecordActiveRecord

● Relation now done via getter instead of relations() method

● Getter returns ActiveQuery that extends Query

ActiveRecordActiveRecord

● Method find() replaces method model() which returns ActiveQuery instance instead of the extended CactiveRecord model instance.

Many MoreMany More

● Assets Bundling● Static Helpers● ActiveForm● Auto Quoting Column Names● User and Identity● Better URL Management

More to comeMore to come

● Better Extension management● Response/Request● Integration with Composer● Widgets (Menu, Pager, Captcha)● NoSQL wrapper● MessageQueue wrapper

WarningWarning

● Yii2 is still in heavy development● It's not even in Alpha phase● What I talk about right now can be obsolete

next week● Fork the github

– http://github.com/yiisoft/yii2

● Try installing● Put your idea and your fix

What's NewWhat's New

● Generators● “Finally” Keyword● Password Hashing API● Bundled OPcode cache● Class name to scalar● Array dereferencing● And many more...

GeneratorGenerator

● Simple iterator without implementing “Iterator” interface

● Iterate result without building array in memory– Exceed memory limit– Time consuming

● Introduces the keyword 'yield'

'Finally' keyword'Finally' keyword

● Just like the one in Java● Mostly concerns with resource handling

– Prevent resource leaking

● Block in `finally` will be executed no matter if the exception caught or not

Bundled Zend OpCacheBundled Zend OpCache

● is ZendOptimizerPlus by Zend

– https://github.com/zendtech/ZendOptimizerPlus

– provides faster PHP execution through opcode caching andoptimization

– storing precompiled script bytecode in the shared memory

● There is also APC (Alternative PHP Cache)

– not really maintainable● Zend OpCache is now bundled with PHP5.5

– You can still install it in PHP5.2, PHP5.3, PHP5.4

Password Hashing APIPassword Hashing API

● password_hash()– Can set the algorithm, the cost, the salt– The value returned will contain the algorithm, the

cost, the salt, and the hash itself.– Only need 1 storage (or 1 column in table).

● password_verify()– Only take the plain password and the hash result
