You can do this one of two easy ways. The way of personal choice is to make your radio/check boxes using an array. eg:

<input type=radio name="radios[quest1]" value="1"> quest1
<input type=radio name="radios[quest2]" value="2"> quest2

etc

In PHP, once the form is submitted, PHP takes all of those values and creates an array in $_POST [$HTTP_POST_VARS prior to 4.1.0] and you can just use a foreach() loop to iterate thru the radios[] array. eg,

foreach($_POST['radios'] as $question) {
// do something...
}

The other easy way is to use PHP's variable variable capabilities.

eg, in your case:

for($i = 1; $i < 5; $i+=2) {
echo "Question Answer: " . ${"radiobutton".$i};
}

HTH. (Check the manual for more info on variable-variables).
