php5.2 JSON does not correctly handle Chinese, GB-encoded solutions

 json_encode to Chinese processing is a problem, not processing GB encoding, all GB code will be replaced with empty characters, there is a good solution, you can refer to the following

php5.2 's new JSON feature is very popular, but tests have found that,  Json_encode has a problem with Chinese processing,  1. GB encoding cannot be processed, and all GB encodings are replaced with the null character .  2. UTF8 encoded Chinese is encoded into Unicode encoding, equivalent to the result of the JavaScript escape function processing .  code as follows:/*    in order to use JSON correctly, we should first use UTF8 encoding on the code, Then we can get the correct result by slightly processing the return result of the Json_encode.   I've written a simple class that wraps the two functions,  **/  class json{  public static function encode ($STR) {  $code = Json_e Ncode ($STR);  return Preg_replace ("#u ([0-9a-f]+) #ie", "Iconv (' UCS-2 ', ' UTF-8 ', pack (' H4 ', ' 1 '))", $code); }     public static function decode ($STR) {  return Json_decode ($str); } } //When used   &N Bsp Json::encode ($code);  Json::d ecode ($code); /** This will correctly handle UTF8 encoded Chinese.     PS: for GB-encoded Chinese, we can be encoded in the first UTF8 encoding, and then coding, decoding the time to do a UTF8-> GB conversion on it.   Other general Json_encode results we are back to the client to use, we can actually use the JavaScript unescape function to decode the Unicode encoded Chinese, so as to restore the correct Chinese.     or used: $title = mb_convert_encoding ($title, ' html-entities ', $this->_outcharset);//Normal display   * * * /&nbSp
