    What about decoding, modify the array and then encoding back? – Fabio Jun 03 '13 at 18:03

Firstly, I'll just note the JSON you showed isn't valid (it's missing a comma :P), but here is the answer:

You have to load it in.

$data = json_decode($json, true);

($json should be the JSON, and true is to specify to decode as associative array where necessary)

then add your element,

$data[] = array('id'=>4, 'name'=>'abcdef', 'value'=>'abcdefg');

and then you can recode it as JSON

$json = json_encode($data);
