how do I get [{}] in JSON? If I encode array() in PHP, the JSON result is []. What is [{}] in JS anyway?

Thanks

[{}] is an array containing a single empty object. –  Kevin Stricker Sep 25 '11 at 20:04

you can use: array(new stdClass) which when json_encoded, should end up to be [{}]

To answer your second question of "what is [{}] anyway?", well it is simple:

it's an array, whose only element is an object with no members in it.

[{}] is an array containing an object. JSON is an object and you can have a JSONArray within it and more objects within that. Don't overthink the data structure :)
