PHP array to JSON display a code in Chinese, to explain

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 (+ + $recursive _counter > 1000) {
        Die (' Possible deep recursion attack ');
    }
    foreach ($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. PHP JSON English Coding

------Solution--------------------
Cough you can replace ' $function ' with the value of the parameter $function.
------Solution--------------------
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);
