XML PHP

[TheDigglerUK]

Hi, i have included some code which doesnt extract all of what i need, what am i doing wrong?

<?

$api = "http://maps.googleapis.com/maps/api/geocode/xml?address=10+sapphire+street+blackburn&sensor=false";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$res = curl_exec($ch);

if ($res) {

$address = $res[formatted_address];

}

print $address;

?>

Thanks in advance, jules
