Json_encode UTF-8 Chinese garbled problem in PHP

Recently in the interface code used to Json_encode, found on the internet said Json_encode encoding set to UTF-8 Chinese will not garbled, verified that this method is really effective, but do not know why, the code after a period of time is not very useful. Here's your solution to the json_encode. There is a better way please share it!

The first type:

This simple to do a code conversion, Urlcode and then return the desired array

This is enough for my code.

Code to copy code as follows
public static function Encodeoperations ($array)

{

foreach ((array) $array as $key = + $value) {

if (Is_array ($value)) {

Encodeoperations ($array [$key]);

} else {

$array [$key] = UrlEncode (mb_convert_encoding ($value, ' UTF-8 ', ' GBK '));

}

}

return $array;

}

The second type:

This is seen on the internet, and then there is a comment that there will be an infinite loop problem, but this is obviously very comprehensive, and then I do have after the test, posted here for reference only

Code to copy code as follows

/**************************************************************

Function Encodeoperations (& $array, $function, $tocode =false, $oldcode =false, $apply _to_keys_also = False)

{

foreach ($array as $key = = $value) {

if (Is_array ($value)) {

Encodeoperations ($array [$key], $function, $apply _to_keys_also);

} else {

if ($tocode && $oldcode) {

if (function_exists (mb_convert_encoding)) {

$value = mb_convert_encoding ($value, $tocode, $oldcode);

}else{

return "error";

}

}

$array [$key] = $function ($value);

}

if ($apply _to_keys_also && is_string ($key)) {

$new _key = $function ($key);

if ($new _key! = $key) {

$array [$new _key] = $array [$key];

Unset ($array [$key]);

}

}

}

return $array;

}

/****from:http://www.111cn.net/phper/31/66729.htm**********************************************************

function JSON ($array) {

Arrayrecursive ($array, ' UrlEncode ', true);

$json = Json_encode ($array);

Return UrlDecode ($json);

}

If the return to Chinese is null, we need to convert the character to uft8 or use UrlEncode to compile the call first.
