PHP Json_encode incompatible with Json_unescaped_unicode solutions, Jsonencodeunicode

PHP5.4 support Json_unescaped_unicode This parameter, this parameter is to let Chinese characters in Json_encode without escaping, reduce the amount of data transfer. But in the PHP5.3, you have to write a function to achieve, the following is the workaround:

/*** JSON encoding of variables * @param mixed value to encode value, except for resource type, can be any data type, the function will only accept UTF-8 encoded data * @return String return value The JSON form of the value */function json_encode_ex ($value) {if (Version_compare (php_version, ' 5.4.0 ', ' < ')) {  $str = Json_encode ($value);  $str = Preg_replace_callback (         "#\\\u ([0-9a-f]{4}) #i",         function ($matchs)         {           return iconv (' Ucs-2be ', ' UTF-8 ', pack (' H4 ', $matchs [1]));         },          $str         );  return $str; } else {  return Json_encode ($value, Json_unescaped_unicode);}}

Determine the version of PHP, if less than 5.4 use a custom function to implement, if the version 5.4 and later use Json_unescaped_unicode.

The above is the PHP json_encode incompatible Json_unescaped_unicode solution, I hope to give you a reference to learn more PHP syntax, we can pay attention to the "PHP5 online manual", but also hope that we support a lot of help the home.
