This article introduces how to solve the gbk garbled characters passed by PHP arrays to JavaScript and json_encode. The following describes how to create a JSON function.

10. Function arrayRecursive (& $ array, $ function, $ apply_to_keys_also = false)
11. {
12. Foreach ($ array as $ key => $ value ){
13. If (is_array ($ value )){
14. ArrayRecursive ($ array [$ key], $ function, $ apply_to_keys_also );
15. } Else {
16. $ Array [$ key] = $ function ($ value );
17. }

35. Function JSON ($ array ){
36. ArrayRecursive ($ array, 'urlencode', true );
37. $ Json = json_encode ($ array );
38. Return urldecode ($ json );
39. }
40. Database Connection value to array $ array1
41. The code is as follows:
42. $ Dbcnx = @ mysql_connect ("localhost", "root", "1234 ");
43. If (! $ Dbcnx ){
44. Echo ("Unable to connect to the". "database server at this time .");
45. Exit ();
46. }
47. If (! @ Mysql_select_db ("pms ")){
48. Echo ("Unable to locate the joke". "database at this time .");
49. Exit ();
50. }
51. Mysql_query ("set names 'gb2312 '");
52. $ Q = mysql_query ("select * from ability where ALV = 1 ");
53. While ($ row = mysql_fetch_array ($ q )){
54. $ Array1 [] = $ row [AName];
55. }

Array array1 is passed to JavaScript to array ability1

1. Script
3. Var ability1 = ;
4. Var a = eval ("ability1 ");
5. Alert (a [0]);
6. Script

Another method to solve json Chinese garbled characters is as follows:

2. /* Process json_encode Chinese garbled characters */
3. $ Data = array ('game' => 'ice-fire status', 'name' => 'Thorn Spirit ', 'Country' => 'ice-Frome status ', 'level' => 45 );
4. Echo json_encode ($ data );
5. Echo"
   ";
6. $ NewData = array ();
7. Foreach ($ data as $ key => $ value ){
8. $ NewData [$ key] = urlencode ($ value );
9. }
10. Echo urldecode (json_encode ($ newData ));
11. ?>

Later, I consulted someone and I could use base64 encoding. However, base64 encoding cannot be placed in URLs. Baidu explained this as follows: standard Base64 is not suitable for direct transmission in URLs, because the URL encoder will convert the "/" and "+" characters in the standard Base64 into the form of "% XX, these "%" signs need to be converted when they are stored in the database, because "%" has been used as a wildcard in ansi SQL.

However, my data is sent through POST, not in the HTTP head, but in the message-body, so it is not affected.

Json_encode can only accept UTF-8 data

For example, if 'signature' is changed to 'u80e5' after json_encode processing, the Chinese part of the final json is replaced with unicode encoding. What we need to solve is to convert the object to json and ensure that the Chinese character inside the object still appears in json as normal Chinese. now it seems that only json_encode can not be used.

My solution: perform url encoding for the Chinese fields in the class first, then perform json encoding (jsonencode) for the object, and finally url decoding (urldecode) json, that is, the final json. the Chinese in it is still the Chinese! The test code is as follows:

2. Class myClass {
3. Public $ item1 = 1;
4. Public $ item2 = 'Chinese ';
5. Function to_json (){
6. // Url encoding to avoid converting Chinese to unicode using json_encode
7. $ This-> item2 = urlencode ($ this-> item2 );
8. $ Str_json = json_encode ($ this );
9. // Url decoding. after converting json, all attributes are returned, so that the object attributes remain unchanged.
10. $ This-> item2 = urldecode ($ this-> item2 );
11. Return urldecode ($ str_json );
12. }
13. }
14. $ C = new myClass ();
15. Echo json_encode ($ c );
16. Echo'
    ';
17. Echo $ c-> to_json ();
18. Echo'
    ';
19. Echo json_encode ($ c );
20. Echo'
    ';
21. Echo json_encode ('authorization ');
22. ?>

Program output result:

1. {"Item1": 1, "item2": "u4e2du6587 "}
2. {"Item1": 1, "item2": "Chinese "}
3. {"Item1": 1, "item2": "u4e2du6587 "}
4. "U80e5"
