Examples of groups attach operation

1. Examples of a means of function urlencode

   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 my_json($array) {
       arrayRecursive($array, 'urlencode', true);
       $json = json_encode($array);
       return urldecode($json);
   }
   $arr = [
       'a'  => 123,
       'b'  => 456,
       'http://www.jjxhp.com/abc/sasa.php' => 'tstst你好',
       'http://www.baidu.com/' => '我们都是好人吧',
       'rew你好' => 'dsdsqwq'
   ];
   
   $str = my_json($arr);
   
   file_put_contents(__DIR__.'/json_str.txt', $str);
   

2. Examples of two, and by json_encode stripslashes

   $new_str = json_encode($arr, JSON_UNESCAPED_UNICODE);
   file_put_contents(__DIR__.'/new_json_str.txt', $new_str);
   $new_str1 = stripslashes($new_str);
   file_put_contents(__DIR__.'/new_json_str1.txt', $new_str1);
