　　@set_time_limit();
//貼吧名稱
$tbname = "mugen";
//相冊ID
$tid = "";
//圖冊頁url模版
$galleryurltpl = "%s&tid=%s";
//本地的目錄
$savepath = "R:/images/";
//帖子子文件夾
$filedir = $savepath$tid;
//圖片文件
$filenametpl = $filedir"/%sjpg";
//圖冊頁url
$galleryurl = sprintf($galleryurltpl $tbname $tid);

　　//返回的json數據
$retjson = file_get_contents($galleryurl);
$retarray = json_decode($retjson true);
//圖片列表
$piclist = $retarray[data][pic_list];

　　//目錄是否存在
if(!is_dir($filedir))
mkdir($filedir);
foreach($piclist as $pic){
$pic_id = $pic[img][original][id];
$url = "$pic_id"jpg";
$filename = sprintf($filenametpl $pic_id);
//下載圖片
$imagebin = file_get_contents($url);
//保存圖片
file_put_contents($filename$imagebin);
}
