How to create a JSON object
json, php
Solution
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.
Problem
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 }.
