Code notes:
Note that when getting the associative array from the DB all elements must contain keys otherwise json_decode() will throw a "syntax error" or similar.

  $keywords =  explode(" ", $data);

        $k_db = keywords_list::all()->toArray();

        var_dump($k_db[0]["keywords"]);

        $jf = (string)$k_db[0]["keywords"];

        var_dump($jf);

        // $json_a = json_encode($jf, true);
        trim($jf);

        $json_a = json_decode($jf, true);

         switch (json_last_error()) {
        case JSON_ERROR_NONE:
            echo ' - No errors';
        break;
        case JSON_ERROR_DEPTH:
            echo ' - Maximum stack depth exceeded';
        break;
        case JSON_ERROR_STATE_MISMATCH:
            echo ' - Underflow or the modes mismatch';
        break;
        case JSON_ERROR_CTRL_CHAR:
            echo ' - Unexpected control character found';
        break;
        case JSON_ERROR_SYNTAX:
            echo ' - Syntax error, malformed JSON';
        break;
        case JSON_ERROR_UTF8:
            echo ' - Malformed UTF-8 characters, possibly incorrectly encoded';
        break;default:
            echo ' - Unknown error';
        break;    }

        echo PHP_EOL;

        var_dump($json_a);

        $string='{"name":"John Adams"}';

        var_dump($string);

        $json_b=json_decode($string,true);

        var_dump($json_b);

        var_dump($keywords);

The core of the keyword comparator and filter is there.
Closing this for now.

Open a new one for advancing the filter.
