PHP forms which retain value on submit

Ok so I got a form and usability is important to me. If the user completes the form and then hits submit but there are errors on the form I have set values to echo back

e.g. <input class="input_phone" name="phone" type="text" value="<?php echo $_POST['phone']; ?>" maxlength="15" />

The value entered will be back in the form field so that the user doesn't have to retype every field.

How do i achieve the same effect with radio buttons?

<input class="radio" name="q1" type="radio" value="YES">

If i set the value to $_POST['q1'] How do I set it to YES?

if isset($_POST['q1']){
   echo '<input class="radio" name="q1" type="radio" checked="checked" value="YES">';
}else{
   echo '<input class="radio" name="q1" type="radio" value="NO">';
}

It is same with input text, just with attribute checked.

<input class="radio" name="q1" type="radio" value="YES" <?php echo $_POST['q1'] === 'YES' ? 'checked' : ''; ?>>
