How to get weekdays in drop down in cakephp, with a default day selected?

Hi all,

I want the weekdays to be displayed in a drop down in cakephp, with a default
day selected.
My code is as follows
echo $form->input('Weekday', array('options' => array
('Monday','Tuesday','Wednesday','Thursday', 'Friday','Saturday',
'Sunday')));
When I do like this it stores 0 value in database instead of day name.
Also I want to set a default selected weekday .
Please help!!!

Thanking you..........
