Download the latest official php payment demo and directly modify the necessary configuration information.
There is no error when you go to the blank page during the payment process, whether it is h5 payment or scanning payment.

Curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, 2); // strict verification

Curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, FALSE); // strict verification
