PHP JSON Chinese encoding

When I passed the array into JSON format in PHP, I found that Chinese would become a strange encoding. So on the Internet to find a solution, see a lot of people with the following two functions solved:

Function arrayrecursive (& $array, $function, $apply _to_keys_also = False) {    static $recursive _counter = 0;    if (+ + $recursive _counter >) {die        (' possible deep recursion attack ');    }    foreach ($array as $key = + $value) {        if (Is_array ($value)) {            arrayrecursive ($array [$key], $function, $apply _ to_keys_also);        } else {            $array [$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]);    }} $recursive _counter--;}

function JSON ($array) {arrayrecursive ($array, ' UrlEncode ', true), $json = Json_encode ($array); return UrlDecode ($json);}

I tested the next really can solve the problem, so carefully studied the next code, found the following code does not know what it means:

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

I output $array[$key] before and after this sentence, and I found this sentence to turn Chinese into a string of codes.
Please explain what $function ($value) means.

Cough you can replace ' $function ' with the value of the parameter $function.

Defined
Function arrayrecursive (& $array, $function, $apply _to_keys_also = False)
$array [$key] = $function ($value);

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

So $array [$key] = $function ($value);
is $array [$key] = UrlEncode ($value);

Uh.. All right.. Is the parameter passed in. I'm low-end ...

Defined
Function arrayrecursive (& $array, $function, $apply _to_keys_also = False)
$array [$key] = $function ($value);

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

So $array [$key] = $function ($value);
is $array [$key] = UrlEncode ($value);

So it seems that the function of these two functions is to first urlencode each value in the array, then json_encode into JSON format, and finally the JSON-formatted string urldecode. Thank you. Look at the code, you can't even turn your head.

This function is for GBK encoded data.
For utf-8 data, this should not be necessary.
