Php5.2 Json cannot properly handle Chinese and GB encoding Solutions

The json function added by php5.2 is very popular, but it has been tested and found that,
Json_encode is problematic in processing Chinese characters,
1. Cannot process the GB encoding. All the GB encoding will be replaced with null characters.
2. UTF-8 encoded Chinese characters are encoded as unicode, which is equivalent to the processing result of the javascript escape function.
Copy codeThe Code is as follows:
/*

In order to use json correctly, we should first adopt utf8 encoding in encoding, and then slightly process the returned results of json_encode to get the correct results.
I wrote a simple class and wrapped the two functions,
**/
Class Json {
Public static function encode ($ str ){
$ Code = json_encode ($ str );
Return preg_replace ("# \\\ u ([0-9a-f] +) # ie", "iconv ('ucos-2', 'utf-8', pack ('h4 ', '\ 1') ", $ code );
}

Public static function decode ($ str ){
Return json_decode ($ str );
}
}
// When using

Json: encode ($ code );
Json: decode ($ code );
/** In this way, utf8 Encoded chinese characters can be correctly processed.

PS: for Chinese Characters in GB encoding, we can convert them into UTF8 encoding Before encoding. During decoding, we can convert them into utf8-> gb.
In addition, the result of json_encode is generally returned to the client for use. In fact, we can also use the javascript unescape function to decode the unicode-Encoded chinese characters to restore them to the correct Chinese characters.

Alternatively, use: $ title = mb_convert_encoding ($ title, 'html-ENTITIES ', $ this-> _ outCharset). // The data is normally displayed under any encoding.
