Adding an array in an existing key in an associative array PHP

Question

Title sounds a bit convoluted but the title itself is pretty self-descriptive I think.

Assume that I have an associative array like this:

$data['blog_info'] = array(
   "title" => "Adventure",
   "author" => "Yo"
);

Now, I would like add to the current key 'blog_info" another set of key => value array. so the result should be :

$data['blog_info'] = array(
   "title" => "Adventure",
   "author" => "Yo",
   "ISBN" => "23423498"
);

so for example I would like to add "ISBN" => "23423498" inside this 'blog_info' key. How am I able to achieve this? (but by going like $data['blog_info'].push("ISBN" => "23423498") etc?)

What would the result look like? Also, the {..} are incorrect. — deceze

In PHP array_push or the [] operator would allow you to push an item to an array but since you have an associative array (Strings as keys) you should use $data['blog_info']['ISBN'] = '23423498'; to achieve your desired result. See my answer below. — Jonathon

The below will achieve it ($data['blog_info'] is just an array).

$data['blog_info']['ISBN'] = '23423498';

In PHP you don't need the curly braces { and } in this context.

$data['blog_info'] = array(
   "title" => "Adventure",
   "author" => "Yo"
);

Try something like

$data['blog_info']['ISBN'] = '23423498';
