Radio buttons allow the user to select a single value from a set of possible values. If you wanted to create a rating system, you could display a set of radio buttons with the values 1-5 and allow the user to select one and only one value.
The Zend_Form_Element_Radio class contains additional setters that are required for a successful implementation (see Table 4-7).
