Phpjson_encode implementation and Chinese garbled code solution

The json_encode () built-in function (php52) in php can be used to transfer data in php well with other languages and use it, this function converts a value to a json data storage format.

The json_encode () built-in function (php> 5.2) in php can be used to transmit and use data in php with other languages, this function converts a value to a json data storage format.

1. $ Arr = array ('a' => 1, 'B' => 2, 'C' => 3, 'D' => 4, 'E' => 5 );
2. Echo json_encode ($ arr );
3. // Result
4. // {"A": 1, "B": 2, "c": 3, "d": 4, "e": 5}

The following describes a json_encode Chinese garbled problem:

The solution is to use the urlencode () function to process the following. before json_encode, urlencode () is used to process all the content in the array, and json_encode () is used to convert the content into a json string, finally, use urldecode () to convert the encoded Chinese characters back.

1. Function arrayrecursive (& $ array, $ function, $ apply_to_keys_also = false)
2. {
3. Static $ recursive_counter = 0;
4. If (++ $ recursive_counter> 1000 ){
5. Die ('possible deep recursion attack ');
6. }
7. Foreach ($ array as $ key => $ value ){
8. If (is_array ($ value )){
9. Arrayrecursive ($ array [$ key], $ function, $ apply_to_keys_also );
10. } Else {
11. $ Array [$ key] = $ function ($ value );
12. }
13.  
14. If ($ apply_to_keys_also & is_string ($ key )){
15. $ New_key = $ function ($ key );
16. If ($ new_key! = $ Key ){
17. $ Array [$ new_key] = $ array [$ key];
18. Unset ($ array [$ key]);
19. }
20. }
21. }
22. $ Recursive_counter --;
23. }
24.  
25. /*************************************** ***********************

33. Function json ($ array ){
34. Arrayrecursive ($ array, 'urlencode', true );
35. $ Json = json_encode ($ array );
36. Return urldecode ($ json );

38. $ Array = array

Application instance:

1. $ Servname = "localhost ";
2. $ Sqlservname = "root ";
3. $ Sqlservpws = "123456 ";
4. $ Sqlname = "lock1 ";
5. $ Db = mysql_connect ($ servname, $ sqlservname, $ sqlservpws) or die ("database connection failed ");
6. Mysql_select_db ($ sqlname, $ db );
7. $ SQL = "select * from t_operater ";
8. $ Result = mysql_query ($ SQL );
9. $ Rows = mysql_num_rows ($ result );
10. While ($ obj = mysql_fetch_object ($ result ))
11. {
12. $ Arr [] = $ obj;
13. }
14. Echo '({"total": "'. $ rows. '", "results":'. json_encode ($ arr ).'})';
