php - Can we post Unchecked Radio Button value? -

i have situation need unchecked radio button value. possible send unchecked radio button value through form in php? if yes, can please explain?

<input type="hidden" name="myfield" value="false" /> <input type="checkbox" name="myfield" value="true" />

both fields have same name, if checkbox isn't checked, hidden field submitted, if checkbox checked, virtually override the hidden field.

on side note, sure radio buttons wouldn't better suited needs, able see definite answer each questions, whereas checkboxes more submitted selected checkboxes. failing assume checkboxes not submitted checked, assumed unchecked.
