Question

I am trying to get the following output format from a CI query and subsequent JSON_encode:

{"clients":{"id":"3","name":"Client Number1"},{"id":"2","name":"Client Number2"},{"id":"1","name":"Test Client"},{"id":"4","name":"Test Client2"}}

Combining the small functions in the controller and the model, I am using:

$query = $this->db->query('SELECT id, name FROM clients ORDER BY name ASC');
        foreach ($query->result() as $row)
        {
            $arr['clients'][] = $row;
        }

        $json = json_encode($arr, JSON_FORCE_OBJECT);
        echo $json;

This code outputs (below) which includes the array index values (“1”, “2”… etc.) How can I remove these index values from the result? Thanks for any help you may be able to give. This one is not a deal-breaking crisis. I could parse them out on the other side of the transaction… but thought the omniscient SO might know how to do this more elegantly!!

{"clients":{"0":{"id":"3","name":"Client Number1"},"1":{"id":"2","name":"Client Number2"},"2":{"id":"1","name":"Test Client"},"3":{"id":"4","name":"Test Client2"}}}

Edit: I was wrong.

Apparently all objects in PHP’s json_encode print as associative arrays, and thus it always prints the keys. At least, that’s the vibe I got from the page on json_encode in the PHP manual.

Removing JSON_FORCE_OBJECT (and using $query->result_array()) gets rid of the keys, but isn’t exactly what you’re looking for:

{"clients":[{"id":"3","name":"Client Number1"},{"id":"2","name":"Client Number2"},{"id":"1","name":"Test Client"},{"id":"4","name":"Test Client2"}]}
