详见 http://qxblog.sinaapp.com/?p=95

1. @set_time_limit(10);
2. //贴吧名称
3. $tbname = "mugen";
4. //相册ID
5. $tid = "2124904411";
6. //图册页url模版
7. $galleryurltpl = "http://tieba.baidu.com/photo/bw/picture/guide?kw=%s&tid=%s";
8. //本地的目录
9. $savepath = "R:/images/";
10. //帖子子文件夹
11. $filedir = $savepath.$tid;
12. //图片文件
13. $filenametpl = $filedir."/%s.jpg";
14. //图册页url
15. $galleryurl = sprintf($galleryurltpl, $tbname, $tid);
17. //返回的json数据
18. $retjson = file_get_contents($galleryurl);
19. $retarray = json_decode($retjson, true);
20. //图片列表
21. $piclist = $retarray['data']['pic_list'];
23. //目录是否存在
24. if(!is_dir($filedir))
25. mkdir($filedir);
26. foreach($piclist as $pic){
27. $pic_id = $pic['img']['original']['id'];
28. $url = "http://imgsrc.baidu.com/forum/pic/item/".$pic_id.".jpg";
29. $filename = sprintf($filenametpl, $pic_id);
30. //下载图片
31. $imagebin = file_get_contents($url);
32. //保存图片
33. file_put_contents($filename,$imagebin);
34. }
35. ?>
