Kohana VS Yii

By Kemal Delalic (kemal.delalic@gmail.com)

Kohana & VS Yii

Two different worlds.

Framework buzz

• 30+ modern PHP frameworks• Different approaches• Hard to choose• Even harder to follow

“Let’s fix what we have”

• EllisLabs’s slow development• Trying to improve CodeIgniter• Community rejection• BlueFlame

“Let’s make it better”

• PHP5• Independant• Faster development

Kohana 2

“Let’s make it much better”

• Complete rewrite• Keep it simple• No magic

Kohana 3

Kohana and I

• Used major frameworks for actual development before:Zend Framework, Symfony, CakePHP, CodeIgniter, etc.• Had to work on a Kohana 3.0.0.

project• “Man, this looks bad”

STRESS

• I have to install new PHP?• Why aren’t method names like in

Zend Framework?• Feels “limited”?• How to use this after ZF which is

so ... awesome and full of everything?• Where is the documentation?

REVELATION

PHP 5.2

Because it was already here.

Strict development and conventions.

Extremely strict.

Code is a symphony

and you feel like an artist writing it

Write your own code

instead of having it generated for you

No magic stuff

because nothing happens out of nowhere

DRY

You should never repeat yourself.

Speed

So fast that no one seems to benchmark against it.

Makes sense

Everything is isolated and in it’s place

Unit tested

Having something safe and tested can’t be bad.

The Core

Only what PHP misses natively

Full UTF-8 support

Because 6 isn’t coming soon

Cascading File System

You don’t know how much you always needed it.

Use Class, extend Kohana_Class

HMVC

(Hierarchical Model-View-Controller)

RFC 2616

Speaking of DRY

Routes help you

not to get lost

Profile

__(‘Internationalization’)

As easy as it can be

HelpersClasses like any others• Powerful toolset

– I18n– Inflector– Log– Num– Security– Session– Text– Upload– URL– UTF8– Validation

Modularity

Force powered by CFS

Cache

• Driver support – all popular drivers• Very easy to use and change driver later

CodeBench

• Easy benchmarking interface on application level

Database

• Powerful object oriented interface• Multiple driver support, MySQL and PDO by

default

Image

• Provides extremely easy interface for image manipulation

• Feels like Photoshop

ORM

• ActiveRecord pattern• Respect and be respected (conventions)

Unittest

• Web interface for running all unit tests from a single place: app, modules, framework

Userguide

• All framework documentation in one place• Application’s API documented “on-the-fly”• Perfect for collaboration and new developers

arriving to the project

Community modules

• 500+ modules• Use Zend Framework or any other library as a

module• Obvious Kohanas’ affection on module

authors’ code quality

People behind Kohana

Small, yet very elite community

Rasmus Lerdorf

is well known for “hating” frameworks
