Try this：
$contract = new Contract(rpcurl, abi);

    $contract->at(tokenAddress)->call('balanceOf', address, [
        'from' => address,
    ], function ($err, $result) use ($contract) {
        if ($err !== null) {
            $this->res['err'] = $err->getMessage();
        }
        if (isset($result)) {;
            $bn = Utils::toBn($result[0]);
            $this->res['amount'] = bcdiv($bn->toString(), 10 ** 18, 18);
        }
    });
