using multiple radio button

When we use multiple radio buttons with same name in Yii many people have the problem on getting the value of the selected radiobutton. The radioButtonList can be used for that, but if we need to use radioButton itself to place the button any where in a view, we need to include one more parameter in htmloption array().

'uncheckValue'=>null

Usage

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

echo 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
));

so we can place the radio button anywhere on the page.
