I am returning a fatal error function must be a string in my php webhook for database fulfillment

Question

I am returning a fatal error saying function must be a string in my webhook database fulfillment. I want to be able to read and write to MySQL database

    $firstname
(isset($update["queryResult"]["parameters"]["firstname"])
? $update["queryResult"]["parameters"]["firstname"]
:null
);
    $lastname
(isset($update["queryResult"]["parameters"]["lastname"])
?$update["queryResult"]["parameters"]["firstname]
:null
);
    $policynumber
(isset($update["queryResult"]["parameters"]["policynumber"])
?$update["queryResult"]["parameters"]["policynumber"]
:null
);
    $id
(isset($update["queryResult"]["parameters"]["id"])
?$update["queryResult"]["parameters"]["id"]
:null
);

I must be able to read and write to my database but instead it is returning the fatal error on these lines of code. I would appreciate your help

Yes, it is supposed to get the value from the user input from the dialogflow bot — user11060150, Aug 09 '19 at 07:19

just assign the value to the variable

$firstname = (isset($update["queryResult"]["parameters"]["firstname"])?$update["queryResult"]["parameters"]["firstname"]:null);
$lastname = (isset($update["queryResult"]["parameters"]["lastname"])?$update["queryResult"]["parameters"]["firstname"]:null);
$policynumber = (isset($update["queryResult"]["parameters"]["policynumber"])?$update["queryResult"]["parameters"]["policynumber"]:null);
$id = (isset($update["queryResult"]["parameters"]["id"])?$update["queryResult"]["parameters"]["id"]:null);
