2014 YII.LARRYULLMAN.COM Good morning and welcome to my presentation on the Yii framework. Speciﬁcally focusing on version 2 of the framework, currently in beta and due for a proper release this summer. ! In creating this presentation, I asked myself: What is it that I want to say about the Yii framework? ! http://www.yiiframework.com/wiki/490/creating-a-simple-crud-app-with-yii2-revised-12-20-2013/ https://github.com/yiisoft/yii2-mongodb
Yii is pretty fast. ! Not sure if you’ve seen those benchmarks for creating a “Hello, World” site using a framework. Which, of course, is something you’d never use a framework for. Plus, I could, for example, make a Yii site that runs quickly and a Code Igniter site that performs poorly, because I don’t know Code Igniter. ! But, no, I’m not here to show you benchmarks, either.
THAT YII IS BETTER THAN X FRAMEWORK CONVINCE YOU TO SWITCH FRAMEWORKS TELL YOU WHY YOU MIGHT LIKE YII TELL YOU WHY I LIKE YII GIVE YOU AN OVERVIEW SHOW CODE HIGHLIGHT YII2 $MYGOALSTODAY === So what am I here for? [[GO THROUGH FALSE]] I’m not a framework expert. I haven’t tried them all and I certainly haven’t mastered them all. So what am I doing here? [[GO THROUGH TRUE]] ! I think we all know there’s a huge beneﬁt in knowing more than one framework. Perhaps that second framework should be Yii, if it’s not already. ! For me, for those of you wondering, Yii is my ﬁrst framework, and maybe Zend is my second maybe. I’ve not tried Laravel, but I’ve heard nothing but good things about it.
RECORD (AR) & PHP DATA OBJECTS (PDO) FLEXIBLE AND EXTENDIBLE GREAT FOR ADVANCED CASES SCALES WELL JQUERY BUILT-IN As for what you might like about Yii, [[WALK THROUGH]] ! Active Record for Object Relational Mapping (ORM) Flexibility: swap ORM, db library, template library (e.g., to Twig), etc. ! component-based architecture scales well thanks to its caching abilities full-stack, ready-to-use ! high performance is always a goal
A LOT OF THE WORK FOR YOU ACCESSIBLE, YET POWERFUL VERY CONFIGURABLE WORKS WELL WITH THIRD-PARTY SOFTWARE FEELS RIGHT now 5.4 spend 80% of your time working on what makes the site unique great for beginners, but not unlimited for advanced programmers use Zend Framework in parts Reminds me of Ruby on Rails
Yii? How many have used Yii 1? Anyone used Yii 2? Today I’m going to focus on Yii 2. It’s currently in a very stable beta, meaning all the features have been locked down. It’s being cleaned up now, the docs are being ﬁnalized, and the ﬁrst production release should be this summer. ! I wouldn’t use Yii 2 in production today, unless I and extra time, but as Yii 2 is the very near future of the framework, there’s no point in giving a presentation on Yii 1.
AND TIME CLASSES TRAITS INTERNATIONALIZATION SHORT ARRAY SYNTAX & SHORT ECHO TAGS Yii 1 required PHP 5.1; Yii 2 will require PHP 5.4. So the ﬁrst big difference about Yii 2 is that it takes advantage of more recent features of the language. [[WALK THROUGH]] ! namespaces BIG CHANGE, previously preﬁxed all classes with C ! The naming of the namespaces follows the directory structure. For example, `yii\web\Request` indicates the corresponding class ﬁle is `web/Request.php` under the Yii framework folder. You can use any core class without explicitly including that class ﬁle, thanks to the Yii class loader. ! built-in RESTful API support support for NoSQL autoloading, PSR-4, supports third-party autoloaders
SUPPORT SUPPORT FOR NOSQL DATABASES TWITTER BOOTSTRAP 3 CONSOLE APPS Version 2.0 is a complete rewrite of Yii, adopting the latest technologies and protocols. more beautiful, current, and efficient code; more efficient code (e.g., breaking CComponent into Object and Component) ! The framework is installed, and applications are created, using Composer. Extensions are installe via Composer, too. ! Support for PSR, which means lovely autoloaders, and easy support for third-party autoloaders. ! built-in RESTful API support ! support for non-sql (including AR) ! Bootstrap 3 support out of the box complex components wrapped in Yii widgets ! improved console applications
! ORACLE ELASTICSEARCH REDIS MONGODB SPHINX Major improvements for working with databases, including Active Record and query builder an also interact with database directly using a PDO layer or query builder ! Class::ﬁndOne(id) Class:ﬁndAll() Class::ﬁnd() ! / to return an active customer whose ID is 1: $customer = Customer::ﬁndOne([ 'id' => 1, 'status' => Customer::STATUS_ACTIVE, ]); // to return customers whose ID is 1, 2 or 3: $customers = Customer::ﬁndAll([1, 2, 3]);
ADVANCED CONCEPTS Goal is to highlight the framework, and speciﬁcally version 2. Going to use a mixture of code and framework overview Will build up part of an app live Won’t be looking at slides for most of the session Could embarrass myself ! Ask questions at any time
WHAT YOU HAVE GETTING FAMILIAR Terminal > Composer Load page in Safari Load requirements page Show features of main page static about page, working contact page, functional login debugging toolbar (will get back to that) The Site’s folders framework goes into vendor/ The Bootstrap File web/ How Yii Handles a Page Request
Info: Nearly every core class in the Yii framework extends from [[yii\base\Object]] or its child class. This means whenever you see a getter or setter in a core class, you can use it like a property. ! Now broken into yii\base\Object and yii\base\COmponent ! Object deﬁnes getters and setters Component extends object and supports events and behaviors ! you can extend Object if you don’t need events and behaviors ! A property deﬁned by a getter without a setter is read only; a property deﬁned by a setter without a getter is write only. ! case-insensitive ! concept-properties.md
OBJECT Major improvements for working with databases, including Active Record and query builder an also interact with database directly using a PDO layer or query builder ! Class::ﬁndOne(id) Class:ﬁndAll() Class::ﬁnd()
EASILY EXTENDABLE AUTHORIZATION VIA ACCESS CONTROL FILTER ROLE BASED ACCESS CONTROL (RBAC) somewhat automatic, pretty easy to implement ! extend IdentityInterface, normal as User model ! authKey is for autologin ! accessToken is OAuth ! You can also do auth via OpenID LDAP, Twitter, Facebook ! Access Control Filter or RBAC
USER INTERFACE MARKDOWN MONGODB REDIS SMARTY SPHINX SWIFT MAILER TWIG More elaborate ! Often third-party ! http://www.yiiframework.com/extensions/ ! The ones on this list are official Yii extensions. ! About 30 for Yii 2 right now; 1500+ for Yii 1
ZEND DATA Can store single piece of data, pages or page fragments, or database stuff ! conﬁgure and access a cache component ! Yii::$app->cache ! very easy to switch from one to the other as they all extend from the same base set() and get() methods to store and retrieve Yii::$app->cache->set($key, $value); can set expiration time cache dependencies ! use APC for 5.4 or less; Opcache for 5.5 and above -enable the opcache -cache the AR db schema
CONTAINER DATABASE MIGRATIONS l18n: message translation, date, time, & number formatting via PHP intl ! testing with codeception ! smarty and twig support built-in ! console applications now automatically generate help output based upon comment blocks! ! Dependency Injection container (http://martinfowler.com/articles/injection.html) ! database migrations
