Question

I’m trying to return use a JSON object with handlebars. Making a small todo list to learn how to use it.

My PHP API is as follows :

$query = "SELECT *
          FROM table";
try
{
    $db = getConnection();
    $response = $db->query($query);
    $todo = $response->fetchAll(PDO::FETCH_OBJ);
    $bdd = null;
    echo json_encode($todo);
}

It then returns something like :

[{"id":"1","todo":"Do something","who":"Me","is_done":"0"},{"id":"2","todo":"Learn JSON","who":"Me","is_done":"0"}]

But I’d actually need it to be like this :

{todos: [{"id":"1","todo":"Do something","who":"Me","is_done":"0"},{"id":"2","todo":"Learn JSON","who":"Me","is_done":"0"}]}

I tried in my PHP API to add instead of echo json_encode($todo)

echo '{todos: ' . json_encode($todo) . '}';

But it doesn’t work. Any ideas ?

While Pointy’s answer is correct (might want to read about JSON), alternatively you could do this:

echo json_encode(array('todos' => $todo));

PHP associative arrays will be serialized to JSON as objects (json_encode() example in Manual).
