Hello, I am a former CI user and while I feel that YII is much more powerful I still kinda lost about some of its features. Could you, please, help me with this issue:

I have a function that determines user locale and then do some specific stuff depending on locale. it has about 10 lines of code and sets a cookie. Currently I run it in almost every controller using public function init(). I would like to create a model or I think it is a better idea to create a component. Could you please give me an example on how to create a component that outputs "hello world" and then call it from any controller? I hope I will figure the rest by myself. I have read wiki and yii tutorial but still with no luck.

Thank you in advance.

in your components folder create a file
for example Hello.php
inside

class Hello extends CApplicationComponent
{
    public function init()
    {
        echo "hellow world";
    }
}

then in your config/main.php add your component to preload array

return array(
	'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
	'name'=>'My Web Application',
	// preloading 'log' component
	'preload'=>array('log','Hello'),
......

I have already figured out

I have created a file Findlocale.php under protected/components with the following text

<?php
class Findlocale

{

     public static function set($query_string)

     {

           echo 'hello world';
     }

}

the in my controller I used:

Findlocale::set('something');

YII is GREAT!

If you want a full application component you can do:

class MyComponent extends CApplicationComponent
{
    public $someconfig='somedefault';

    public function init() {
        // Init this component
        // $this->someconfig is already available
    }

    public function myblabla() {...}
}

// main configuration:
...
'components'=>array(
    'something'=>array(
        'class'=>'MyComponent',
        'someconfig'=>'someothervalue',
    ),
...

Access from anywhere with:

Yii::app()->something->myblabla();

You can also add 'something' to preload like rudenich suggested (but i'd not use the classname here, it should be the id of a component), to always preload this component. Otherwise it's lazy loaded (on first access).

EDIT:
Fixed example, thanks Muaid.
