I was able to use ontok.com and nusoap.php as described at http://www.ontok.com/wiki/index.php/Geocode#PHP.

I modified the addAddress() function in Phoogle as follows (make sure to get nusoap.php and include it in the file).  This replaces the same code that used file_get_contents:

$server = "www.ontok.com";   // subscribers are emailed a private server with faster response times
$key = "";  // free users do not need key (limit 10 addresses), subscribers w/key (limit 200  addresses)
$q = array($address);
$soapclient = new soapclient("http://$server/geocode/soap");
$result = $soapclient->call("geocode",  array('key'=> $key, 'q'=> $q), "", "");
$pointer = count($this->validPoints);
$this->validPoints[$pointer]['lat']= $result[0]['lat'];
$this->validPoints[$pointer]['long']= $result[0]['long'];
$this->validPoints[$pointer]['passedAddress'] = $address;
$this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;
