Problem solving of Json_encode Chinese Unicode transcoding in PHP

We introduced in the previous article The Json_encode () function in PHP and how to use it, when we work will use Json_encode to deal with Chinese, Chinese will be encoded, become unreadable, similar to "\u***" format, if you want Chinese characters do not transcode , here are three ways to solve the problem of Json_encode Chinese Unicode transcoding!

1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unicode, so the name Incredibles, that is, JSON do not encode UNICODE.

<?phpecho Json_encode ("Chinese", json_unescaped_unicode);//"Chinese"

2. UrlEncode the Chinese characters first and then use the Json_encode,json_encode again after using the UrlDecode to decode, so that the encoded JSON array of Chinese characters will not appear Unicode encoding.

$array = Array (' Test ' =>urlencode ("I Am Test"), $array = Json_encode ($array); Echo UrlDecode ($array);//{"test": "I am a Test"}

3. Decode the Unicode code and decode the function as follows:

function Decodeunicode ($str) {    return Preg_replace_callback ('/\\\\u ([0-9a-f]{4})/I ',        create_function (            ' $matches ',            ' Return mb_convert_encoding (Pack ("h*", $matches [1]), "UTF-8", "ucs-2be"); '        ),        $str);}

4. Example

$arr = Array (' name1 ': "Chinese", ' name2 ': ' Abc12 '); $jsonstr = Decodeunicode (Json_encode ($arr));

Summarize:

This article through three kinds of methods to solve the PHP json_encode Chinese Unicode transcoding problem, I believe that the small partners encountered the same problem can be easily solved!
