mysqli准备语句问题

Question

I'm having an issue with the below code, and cannot work out what i've done incorrectly in preparing my variables for the MySqli query, can anyone help?

I think it may be in the first parameter within bind_param but really am unsure.

Thanks In Advance

I do not use mysqli so I might be well off the mark here but you could perhaps try this:

$stmt =  $mysqli->stmt_init();
if( $mysqli->prepare("INSERT INTO `search_queries`.`search_results`
    (
        `itemkey`,
        `brand`,
        `holidayresort`,
        `duration`,
        `boardbasis`,
        `roomtypedescription`,
        `deeplinkurl`,
        `offerreference`,
        `currency`,
        `priceperadult`,
        `totalpricebeforediscount`,
        `totalprice`,
        `adjustedprice`,
        `mealsincluded`,
        `transfersincluded`,
        `luggageincluded`,
        `hotelidentifiercode`,
        `hotelname`,
        `starrating`,
        `hotelurl`,
        `outbounddeparture`,
        `outbounddepartureairport`,
        `outboundarrival`,
        `outboundarrivalairport`,
        `outboundflightnumber`,
        `outboundairline`,
        `inbounddeparture`,
        `inbounddepartureairport`,
        `inboundarrival`,
        `inboundarrivalairport`,
        `inboundflightnumber`,
