PHP Geocoding question

I'm trying to get lat and long when geocoding an address.

For example this address as $address:

http://www.geocodefarm.com/api/forward/json/c3140ba389a289bd42c51ebe2d72ccc67fb4633c/1058 W Club Blvd,Durham,North-Carolina,27701

Open in new window


This is the code:

 
// Take the address in a variable
	$address = $attorneysStuff['bizAddr'].','.$attorneysStuff['bizCity'].','.$attorneysStuff['bizState'].','.$attorneysStuff['bizZip'];
 
 
$address_url = "http://www.geocodefarm.com/api/forward/json/c3140ba389a289bd42c51ebe2d72ccc67fb4633c/$address";



$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $address_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
 
$response_a = json_decode($response);
 
//Print the provided address in Human readable/ complete Postal address;
echo $address_returned = $response_a->results[0]->ADDRESS->address_returned.'<br />';
 
//Print the Latitude and Longitude of the address
echo $lat = $response_a->geocoding_results[0]->COORDINATES->latitude.'<br />';
echo $long = $response_a->geocoding_results[0]->COORDINATES->longitude;

Open in new window



The problem is echo $address_returned  and echo $lat and echo $long won't print anything: I'm sure there is an error in the print string not in the curl but I can't find it.

When you copy and paste the first string in your browser you can see the json response which is:
