function getResults()
{
var radios = document.getElementsByName("address");    
for (var i = 0; i < radios.length; i++)
{       
if (radios[i].checked) {
var a = radios[i].value

Do this.. 

   $var1 = <?=$_GET["a"]?>;

to communicate a value from JavaScript to PHP do following

$var1 = <?=$_POST["a"]?>;

What you tried is almost correct: 

var a = <?=$_GET["a"]?>;

Since javascript code runs on client-side, but PHP is server-side code, you need to send your JS variables to the server. You can do this using AJAX.

Hint: AJAX calls usually use POST instead of GET.

Replace:

 $var1 = $_GET["a"];

on:

 $var1 = <?=$_POST["a"]?>;
