///////////////////////////////////////////////////////////
// The server access method determines which PHP function
// this code uses to get data from the feed server.
//
// By default, the method used is the fopen function. If
// your web host has disabled this method, you can try the
// fsockopen and cURL methods.
//
// The cURL method is not enabled in PHP by default but is
// the fastest data access method.
//
// To change the access method, change the setting below
// to one of the following values:
// 0 = fopen
// 1 = fsockopen
// 2 = cURL
