方法一：

1. <?php
   
2. $code = json_encode($str);
   
3. $code = preg_replace("#\\\u([0-9a-f]+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $code);
   
4. ?>

方法二： 

1. <?php
   
2. // 将数组转换成Json格式，中文需要进行URL编码处理
   
3. function Array2Json($array) {
   
4.     arrayRecursive($array, 'urlencode', true);
   
5.     $json = json_encode($array);
   
6.     $json = urldecode($json);
   
7.     // ext需要不带引号的bool类型
   
8.     $json = str_replace("\"false\"","false",$json);
   
9.     $json = str_replace("\"true\"","true",$json);
   
10.     return $json;
    
11. }
    
12. function arrayRecursive(&$array, $function, $apply_to_keys_also = false)
    
13. {
    
14.     static $recursive_counter = 0;
    
15.     if (++$recursive_counter > 1000) {
    
16.         die('possible deep recursion attack');
    
17.     }
    
18.     foreach ($array as $key => $value) {
    
19.         if (is_array($value)) {
    
20.             arrayRecursive($array[$key], $function, $apply_to_keys_also);
    
21.         } else {
    
22.             $array[$key] = $function($value);
    
23.         }
    
24.         if ($apply_to_keys_also && is_string($key)) {
    
25.             $new_key = $function($key);
    
26.             if ($new_key != $key) {
    
27.                 $array[$new_key] = $array[$key];
    
28.                 unset($array[$key]);
    
29.             }
    
30.         }
    
31.     }
    
32.     $recursive_counter--;
