How to remove key from json response?

问题

I've got a collection $tree that is being converted to json with Response::json(). The key is being automatically set to the id of the first object. Is there a way to remove this, or restructure with:

'data': [
    { first object },
    { second object}
]

It is currently responding with:

{"1":{"id":"1","parent_id":null,"lft":"1","rgt":"8","depth":"0"...

When I want is:

{'data':[{"id":"1","parent_id":null,"lft":"1","rgt":"8","depth":"0"...

回答1:

Try to use: Response::json(array( 'data' => array_values($yourDataArray) ) );

回答2:

use :

Response::json(array( 'data' => array_values($dataArray) ) );

回答3:

Well, in PHP it would be easy, just use array_values() on the initial array so that it 'forgets' the array indexes (which by the way, is what 'RootName_X' is called in your case:

 $newvalue = array_values( (array)$value );
echo json_encode($newvalue);
