//2 - prepare HTTP request for data. Copy the URL from the RapLink Feed page in RapNet.com: 
// go to: http://www.rapnet.com/RapNet/DownloadListings/Download.aspx, choose your parameters, and click
// generate code. Make sure to specify the columns wanted. This can produce a very long URL.

//prepare to save response as file.
$fp = fopen('import/rapnetfeed.csv', 'wb');
if ($fp == FALSE)

}

//create HTTP GET request with curl 
$request = curl_init($feed_url); // initiate curl object
curl_setopt($request, CURLOPT_FILE, $fp); //Ask cURL to write the contents to a file
curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response
curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins
curl_exec($request); // execute curl post
// additional options may be required depending upon your server configuration
// you can find documentation on curl options at http://www.php.net/curl_setopt
curl_close ($request); // close curl object 
fclose($fp); //close file;
