我想从Json那里得到一些信息
请问我怎样才能拿到它？
curl ：

$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);  
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 3);     
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie: ***"));

$html = curl_exec($ch);
curl_close($ch);

$values = json_decode($html);
$info = $values['a']['new'];
echo "$info";

世珍：

{"a":{"new":"someinfo..."}}

我试图得到里面是什么['新'];
