Due to lack of desired outcome, I can only assume you are trying to get a multidimensional array.

The correct way to achieve this would be to build an array of arrays, and then json_encode the parent array.

$data = array();
$data['fruits'] = array('apple','banana','cherry');
$data['animals'] = array('dog', 'elephant');
$json = json_encode($data);

Following this code, $json will have the following value


It could then be parsed properly by javascript using jQuery.parseJSON()
