I have recently used json_encode in the interface code. I found on the Internet that if the json_encode encoding is set to UTF-8 Chinese, it will not be garbled. It has been verified that this method is indeed effective, but I don’t know why. After using the code for a while It doesn’t work that well after a while. The following is my own solution to json_encode. If you have a better method, please share it!

The first one:

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

This is enough for my code.

Copy the 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,&#39;UTF-8&#39;,&#39;GBK&#39;));
 
}
 
}
 
return $array;
 
}

I saw this on the Internet, and then there were comments saying that there would be an infinite loop problem, but this It is obviously very comprehensive, and it is indeed there after I tested it. It is posted here for reference only.

The code is as follows

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

* 使用特定function对数组中所有元素做处理
 
* @param string &$array 要处理的字符串
 
* @param string $tocode 编码后
 
* @param string $oldcode 编码前
 
* @param string $function 要执行的函数
 
* @return boolean $apply_to_keys_also 是否也应用到key上
 
* @return array $array 是否也应用到key上
 
* @access public
 
*
 
*************************************************************/
 
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;
 
}

function JSON($array) {

$json = json_encode($array);
 
return urldecode($json);
 
}

If the return value for Chinese is null, we need to convert the characters into uft8 or use it first urlencode is used to compile the call.
