PHP JSON Chinese_PHP Tutorial

Using the json_encode() built-in function in php (php > 5.2) can be used so that the data in php can be transferred and used well with other languages.

The function of this function is to convert numerical values ​​into json data storage format.

[php]
$arr = array
(
          'Name'=>'Shia',
‘Age’=>20
);

$jsonencode = json_encode($arr);
echo $jsonencode;
?>

The results of running the program are as follows:

[php]
{"Name":null,"Age":20}

JSON_ENCODE function is encoded in NULL in Chinese. Google is very simple. In order to closely combine with the front end, JSON only supports UTF-8 coding. I think it is the reason for the front-end JavaScript.
[php]
$array = array
(
         'title'=>iconv('gb2312','utf-8','This is the Chinese title'),
        'body'=>'abcd...'
);

echo json_encode($array);
?>

The result of running this program is:

[php]
{"title":"u8fd9u91ccu662fu4e2du6587u6807u9898","body":"abcd..."}
All Chinese in the array disappeared after json_encode or U2353 appeared.

The solution is to use the urlencode() function to process the following. Before json_encode, use urlencode() to process all the contents of all arrays, then use json_encode() to convert it into a json string, and finally use urldecode() to Convert the encoded Chinese back.

[php] 
/***************************************************** **********

* Use a specific function to process all elements in the array
* @param string &$array The string to be processed
* @param string $function The function to be executed
* @return boolean $apply_to_keys_also Whether to also apply to keys
* @access public
*
*************************************************** ***********/ 
function arrayRecursive(&$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--; 
} 
  
/***************************************************** **********
*
* Convert array to JSON string (compatible with Chinese)
* @param array $array The array to be converted
* @return string The converted json string
* @access public
*
*************************************************** ***********/ 
function JSON($array) { 
    arrayRecursive($array, 'urlencode', true); 
    $json = json_encode($array); 
    return urldecode($json); 
} 
 
$array = array 
       ( 
          'Name'=>'希亚', 
          'Age'=>20 
       ); 
 
 
echo JSON($array); 
?> 

     这次成功了，运行结果如下：
[php] view plaincopy
{"Name":"希亚","Age":"20"}
