我使用以下代码从discogs的特定记录中获取数据：
//initialize the session
$ch = curl_init();
//Set the User-Agent Identifier
curl_setopt($ch, CURLOPT_USERAGENT, 'MYAPPNAME/0.1 +http://ymysite.com');
//Set the URL of the page or file to download.
curl_setopt($ch, CURLOPT_URL, $url);
//Ask cURL to return the contents in a variable instead of simply echoing them
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//Execute the curl session
$output = curl_exec($ch);
//close the session
curl_close ($ch);
我可以回显$output，这将给我一个非常复杂的输出：
{"风格"：["蓝调摇滚"，"摇滚"]，"视频"：[{"持续时间"：200，"嵌入"：true，"标题"："滚石乐队-街头斗士"，"描述"："摇滚乐队-街头霸王"，"uri"：http://www.youtube.com/watch?v=qUO8ScYVeDo"｝，｛"持续时间"：2457，"嵌入"：true，"标题"："滚石乐队-乞丐宴会全套专辑（单乙烯基混音）"，"描述"："摇滚乐队-乞丐宴全套专辑"，"uri"："http://www.youtube.com/watch?v=sRu88xttBrA"｝]，"series"：[]，"labels"：[｛"resource_url"："http://api.discogs.com/labels/5320"，"entity_type"："1"，"catno"："SKL 4955"，"id"：5320，"name"："Decca"｝]…还有更多…
例如，我如何使用PHP从"styles"中获取信息，从而输出"Blues Rock，Rock&Roll"？也许我也想从"描述"中获得信息，以输出"滚石乐队-乞丐宴会全专辑（单乙烯基混音）"。
亲切问候Johan
