A new function for json_validate has been added to PHP. 8.3. We could look to use this instead of querying the json_last_error() function for this information (or just not checking properly at all).

There is a polyfill available: https://php.watch/versions/8.3/json_validate#polyfill

We could add this polyfill and recommend that any code working with JSON make use of the json validation.
