With OpenSSL version 1.0 "openssl_x509_parse" would always return "serialNumber" as a string representation of an integer value, while "serialNumberHex" would be a string representation of a hexadecimal number.

This changes when using OpenSSL version 1.1. With OpenSSL version 1.1 the value of "serialNumber" is sometimes (not always) returned as a string representation of a hexadecimal number instead of an integer.

This is due to the following changes in OpenSSL:

Expected result:
  string(39) "269913321572441498538983276629377170905"
  string(32) "CB0F6A32FD527F6C0001000056603DD9"

Actual result:
  string(34) "0xCB0F6A32FD527F6C0001000056603DD9"
  string(32) "CB0F6A32FD527F6C0001000056603DD9"
