json_encode UTF-8 Chinese garbled problem in php.

Recently I have used json_encode in the interface code. I found on the Internet that json_encode encoding is set to UTF-8 Chinese and it will not work. Garbled code, it has been proven that this method is indeed effective, but I don’t know why, the code doesn’t work very well after using it for a period of time. The following is my own solution to json_encode. If you have a better method, please share it!

First type:

This is a simple code conversion, and then return the required array after urlcode

This is enough for my code.

The code is as follows Copy code
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;

}

Second type:

I saw this on the Internet, and there were comments saying that there will be infinite loop problems, but this is obviously very comprehensive, and after I tested it, it did happen. I post it here for reference only

The code is as follows Copy the code

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

*

* Use a specific function to process all elements in the array

* @param string &$array The string to be processed

* @param string $tocode encoded

* @param string $oldcode before encoding

* @param string $function The function to be executed

* @return boolean $apply_to_keys_also whether it is also applied to keys

* @return array $array Whether it is also applied to key

* @access public

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

function encodeOperations (&$array, $function, $tocode=false,$oldcode=false,$apply_to_keys_also = false)

{

foreach ($array as $key => $value) {
(www.111cn.net)
if (is_array($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************************************ *******************************

*

* Convert array to JSON string (compatible with Chinese)

* @param array $array The array to be converted

* @return string converted json string

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

function JSON($array) {

arrayRecursive($array, 'urlencode', true);

$json = json_encode($array);

return urldecode($json);

}

If null is returned for Chinese, we need to convert the characters into uft8 or use urlencode to compile first.
