IOS uses ASIHttpRequest + Json to perform login verification with the server segment script. I am sorry for not carefully explaining how the script interacts. After all, I only use php for the past few days ..

First, let's look at a php client I just wrote:

[Php]View plaincopyprint?

3. $ Arr;
4. Function traverse ($ path = '.')
5. {
6. $ Current_dir = opendir ($ path); // opendir () returns a directory handle. If it fails, false is returned.
7. $ Directory_arr;
8. $ File_arr;
10. $ Directory_index = 1;
11. $ File_index = 1;
13. Global $ arr;
14. $ Arr_index = 0;
16. While ($ file = readdir ($ current_dir ))! = False)
17. {// Readdir () returns an entry in the Open Directory handle.
18. $ Sub_dir = $ path. DIRECTORY_SEPARATOR. $ file; // build the subdirectory path
19. If ($ file = '.' | $ file = '..')
20. {
21. Continue;
22. }
23. Else if (is_dir ($ sub_dir ))
24. {// Perform recursion for directories
25. // Echo 'Directory '. $ file .':
    ';
26. $ String = "Directory ";
27. $ String. = $ directory_index;
28. $ Directory_arr [$ string] = $ file;
29. $ Directory_index ++;
30. Traverse ($ sub_dir );
31. // Print_r ($ directory_arr );
32. }
33. Else
34. {// If it is a file, direct output
35. // Echo 'file in Directory '. $ path.': '. $ File .'
    ';
36. $ File_arr [$ file_index] = $ path. '\'. $ file .'
    ';
37. $ File_index ++;
38. }
39. };
41. $ Arr ["dir_count"] = count ($ directory_arr );
42. // Print_r ($ file_arr );
43. // Print_r (count ($ file_arr ));
44. // Echo'
    ';
45. // Echo "================================ ";
46. // Echo'
    ';
48. // One of them is a titleworkflow first, and the other half is a. txt.
49. $ Arr [$ path] = (count ($ file_arr)-1)/2;
50. }
52. Traverse ('images ');
53. // Print_r ($ arr );
55. // Print_r (json_encode ($ arr ));
57. $ ResultJson = json_encode ($ arr );
58. Echo $ resultJson;
59. ?>

The following page is displayed after the php script is directly run on the server:

This is a demo of getting the current webrootdirectory, the number of directories in the imagesfolder, and the number of .jpg files.

Here is the content of day1:

On the corresponding iOS end, write as follows:

39. If (_ request)
40. {
41. If ([_ request error])
42. {
43. NSLog (@ "error ");
44. }
45. Else if ([_ request responseString])
46. {
47. NSString * result = [_ request responseString];
48. // NSLog (@ "% @", result );
49. NSDictionary * mydict = [result JSONValue];
51. DescribeDictionary (mydict );
52. }
53. }
54. Else
55. {
56. NSLog (@ "request is nil .");
57. }
58. }
60. Void describeDictionary (NSDictionary * dict)
61. {
62. NSArray * keys;
63. Int I, count;
64. Id key, value;
66. Keys = [dict allKeys];
67. Count = [keys count];
68. For (I = 0; I <count; I ++)
69. {
70. Key = [keys objectAtIndex: I];
71. Value = [dict objectForKey: key];
72. NSLog (@ "Key: % @ for value: % @", key, value );
73. }
74. }
76. @ End

This is the result of parsing Json data after calling this Code:
