Question : php syntax

Hi,
when i call the curl.php file in a browser, it displays the location information related to the supply coordinates

<?php
$curl_handle=curl_init();
//curl_setopt($curl_handle,CURLOPT_URL,'http://maps.google.com/maps/api/geocode/json?latlng=$lat,$lng&sensor=false');
curl_setopt($curl_handle,CURLOPT_URL,'http://maps.google.com/maps/api/geocode/json?latlng=53.290695,-6.273949&sensor=false');
curl_exec($curl_handle);
curl_close($curl_handle);

?>

i now want to supply the coordinates in a query string for example,
http://URL/curl.php?lat=53.123456&lng=-6.123456
however I'm having problems with the syntax in the line below when i try to embed the variables in the query string...have played around with it but not getting the correct result
curl_setopt($curl_handle,CURLOPT_URL,'http://maps.google.com/maps/api/geocode/json?latlng=$lat,$lng&sensor=false');

any help appreciated

         
          <?php
$lat = $_GET['lat'];
$lng = $_GET['lng'];
$curl_handle=curl_init();
curl_setopt($curl_handle,CURLOPT_URL,'http://maps.google.com/maps/api/geocode/json?latlng=$lat,$lng&sensor=false');
curl_exec($curl_handle);
curl_close($curl_handle);

?>

curl_exec($curl_handle);
curl_close($curl_handle);
