If you're happy doing it in Javascript, modern varieties of JSON.stringify have an optional argument, which sets the number of spaces to pretty-print with. For example, using an example object from that page:

var foo = {foundation: "Mozilla", model: "box", week: 45, transport: "car", month: 7};
console.log(JSON.stringify(foo, null, 4));

This outputs:

{
    "foundation": "Mozilla",
    "model": "box",
    "week": 45,
    "transport": "car",
    "month": 7
}

June 6, 2012 - You can also see that json_encode takes care of the correct type conversion, so booleans and null are not transformed into strings but use their correct type. Let’s now look into objects: <?php class User { public $firstname = ""; public $lastname = ""; public $birthdate = ""; } $user = new User(); $user->firstname = "foo"; $user->lastname = "bar"; // Returns: {"firstname":"foo","lastname":"bar"} json_encode($user); $user->birthdate = new DateTime(); /* Returns: { "firstname":"foo", "lastname":"bar", "birthdate": { "date":"2012-06-06 08:46:58", "timezone_type":3, "timezone":"Europe\/Berlin" } } */ json_encode($user); ?>

The reason it comes in version 4 which changes a bit the API is the speed. I as wondering how fast it was to use the library and after some tests, it shows it was 6 times slower than the native function.
