whenWhen we use multiple radio buttons with same name in
Yii 
many people have the problem on getting the value of the selected radiobutton.
we can useThe radioButtonList can be used for
that. Butthat, but if we need to use radioButton itself to
place the button any where in a view.

 weview, we need to have include one more parameter
in htmloption array()array().

**'uncheckValue'=>null**

##Usage
~~~
[php]
echo CHtml::radioButton('btn', false, array(
    'value'=>'1',
    'name'=>'btnname',
    'uncheckValue'=>null
)); 
CHtml::radioButton('btn', false, array(
    'value'=>'2',
    'name'=>'btnname',
    'uncheckValue'=>null
)); 

echo
CHtml::radioButton('btn',false,array('value'=>'1','name'=>'btnname','uncheckValue'=>null));

CHtml::radioButton('btn',false,array('value'=>'2','name'=>'btnname','uncheckValue'=>null));
//we can use it in activeRadioButton(), too
echo $form->radioButton($model, 'name', array(
    'value'=>1,
    'uncheckValue'=>null
));
echo $form->radioButton($model, 'name', array(
    'value'=>2,
    'uncheckValue'=>null
));
