JSON Question

Create JSON-object the correct way

I am trying to create an JSON object out of a PHP array. The array looks like this:

$post_data = array('item_type_id' => $item_type,
'string_key' => $string_key,
'string_value' => $string_value,
'string_extra' => $string_extra,
'is_public' => $public,
'is_public_for_contacts' => $public_contacts);

The code to encode the JSON look like this:

$post_data = json_encode($post_data);

The JSON file is supposed to look like this in the end:

"item": {
"is_public_for_contacts": false,
"string_extra": "100000583627394",
"string_value": "value",
"string_key": "key",
"is_public": true,
"item_type_id": 4,
"numeric_extra": 0

How can I encapsulate the created JSON code in the "item": { JSON CODE HERE }.

Usually, you would do something like this:

$post_data = json_encode(array('item' => $post_data));

But, as it seems you want the output to be with "{}", you better make sure to force json_encode() to encode as object, by passing the JSON_FORCE_OBJECT constant.

$post_data = json_encode(array('item' => $post_data), JSON_FORCE_OBJECT);

"{}" brackets specify an object and "[]" are used for arrays according to JSON specification.
