$data = Array ();
$data [' result '] = array ();
Any bar
$data [' result '] = Array (' userid ' = ' 001 ', ' username ': ' Li Ming ');

In JSON, [] means an array, which is characterized by the absence of a key name, which is typically used to represent a value that contains multiple sets of objects. {} represents an object that is characterized by a key value corresponding to it.

$a = Array (
  ' Result ' = = Array (
    Array (' userid ' = ' 001 ', ' username ' = ' li Ming '),
  ),
);

Array_walk_recursive ($a, ' encode ');
Echo UrlDecode (Json_encode ($a));

$a = Array (
  ' Result ' = = Array (
    Array (' userid ' = ' 001 ', ' username ' = ' Zhang Fei '),
    Array (' userid ' = ' 001 ', ' username ' = ' Zhang Fei '),
  ),
);

Array_walk_recursive ($a, ' encode ');
Echo UrlDecode (Json_encode ($a));


function encode (& $item, $key) {
  $item = UrlEncode ($item);
}

{"Result": [{"userid": "001", "username": "Li Ming"}]}

{"Result": [{"userid": "001", "username": "Zhang Fei"},{"userid": "001", "username": "Zhang Fei"}]}
