Unlike JavaScript, which distinguishes between indexed arrays and objects, PHP uses the same internal structure
for both indexed and associative arrays. As a result, when the API returns an empty PHP array, it is interpreted
in JavaScript as an empty array ([]), not an empty object ({}).
This typically occurs when an API module accepts a **prop= query parameter and the user explicitly overrides
its default value by specifying it as empty.
