Php – Sending credit card numbers directly to the Stripe API is generally unsafe

Error says:
An error occurred: Sending credit card numbers directly to the Stripe API is generally unsafe. To continue processing use Stripe.js, the Stripe mobile bindings, or Stripe Elements. For more information, see https://dashboard.stripe.com/account/integration/settings. If you are qualified to handle card data directly, see https://support.stripe.com/questions/enabling-access-to-raw-card-data-apis.

My backend code is:

public function doPayment($paymentRequest)
{

    try {

        $payment_transaction_id = $paymentRequest['payment_transaction_id'];

        $zeroDecimalCurrencies = array('BIF', 'CLP', 'DJF', 'GNF', 'JPY', 'KMF', 'KRW', 'MGA', 'PYG', 'RWF', 'UGX', 'VND', 'VUV', 'XAF', 'XOF', 'XPF');

        if (!in_array($paymentRequest['currency'], $zeroDecimalCurrencies)) {
            $payment_amount = ($paymentRequest['total_value']) * 100;
        } else {
            $payment_amount = $paymentRequest['total_value'];
        }

        $paymentIntentCreate = $this->stripe->paymentIntents->create([
            "amount" => $payment_amount,
            "currency" => $paymentRequest['currency'],
            'payment_method_types' => ['card'],
            'customer' => $paymentRequest['stripe_customer_id']
        ]);

        $paymentIntentConfirm = $this->stripe->paymentIntents->confirm(
            $paymentIntentCreate->id,
            ['payment_method' => $paymentRequest['payment_method_id']]
        );

        $gateWayResponse = PaymentGatewayResponse::create(array('transaction_id' => $payment_transaction_id, 'response' => $paymentIntentConfirm));

        return $paymentIntentConfirm;
    } catch (StripeExceptionCardException $e) {
        ErrorLogger::logError($e);
        return false;
        // Since it's a decline, StripeExceptionCardException will be caught
    } catch (StripeExceptionRateLimitException $e) {
        ErrorLogger::logError($e);
        return false;
        // Too many requests made to the API too quickly
    } catch (StripeExceptionInvalidRequestException $e) {
        ErrorLogger::logError($e);
        return false;
        // Invalid parameters were supplied to Stripe's API
    } catch (StripeExceptionAuthenticationException $e) {
        ErrorLogger::logError($e);
        return false;
        // Authentication with Stripe's API failed
        // (maybe you changed API keys recently)
    } catch (StripeExceptionApiConnectionException $e) {
        ErrorLogger::logError($e);
        return false;
        // Network communication with Stripe failed
    } catch (StripeExceptionApiErrorException $e) {
        ErrorLogger::logError($e);
        return false;
        // Display a very generic error to the user, and maybe send
        // yourself an email
    } catch (Exception $e) {
        ErrorLogger::logError($e);
        return false;
        // Something else happened, completely unrelated to Stripe
    }
    $gateWayResponse = PaymentGatewayResponse::create(array('transaction_id' => $payment_transaction_id, 'response' => $e->getMessage()));
    return ['status' => 0, 'data' => $e->getMessage(), 'message' => 'Payment Failed'];
}

Chat GPT says error is in frontend
Ensure that your frontend correctly tokenizes the card data and sends only the tokenized payment_method_id to the backend.

Any solutions ?
