Answer 1

下面的代码对我有用:

// Cleans up ugly JSON data by removing @attributes tag
function cleanup_json ($ugly_json) {
   if (is_object($ugly_json)) {
      $nice_json = new stdClass();
      foreach ($ugly_json as $attr => $value) {
         if ($attr == '@attributes') {
            foreach ($value as $xattr => $xvalue) {
              $nice_json->$xattr = $xvalue;
            }
         } else {
            $nice_json->$attr = cleanup_json($value);
         }
      }
      return $nice_json;
   } else if (is_array($ugly_json)) {
      $nice_json = array();
      foreach ($ugly_json as $n => $e) {
        $nice_json[$n] = cleanup_json($e);
      }
      return $nice_json;
   } else {
      return $ugly_json;
   }
}

// Convert XML to JSON
function convert_to_json ($xml_string) {
   $xml = simplexml_load_string($xml_string);
   $ugly_json = json_decode(json_encode($xml));
   $nice_json = cleanup_json($ugly_json);
   return json_encode($nice_json, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);
}
