Rubyについて Part 39

Rubyで以下のPHPコードをやろうとするとどうなりますか？

$curl = curl_init();

curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, ‘track=#NowPlaying’);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, ‘http://stream.twitter.com/1/statuses/filter.json’);
curl_setopt($curl, CURLOPT_USERPWD, $_CONFIG['twitter']['username'] . ‘:’ . $_CONFIG['twitter']['password']);
curl_setopt($curl, CURLOPT_WRITEFUNCTION, ‘progress’);
curl_exec($curl);
curl_close($curl);

function progress($curl, $str)
{
print “$str\n\n”;
return strlen($str);
}
