XAMPP is never intended to run a live server. Your choice to do so is contrary even to apachefriends.org's recommendations to avoid such use.
Nevertheless, if you want CURL support, just enable it in your php.ini.
And SSL as well.
Since you're going to ask "how", just uncomment these lines:
...so they look like this:Code:;extension=php_curl.dll ;extension=php_openssl.dllAnd restart the apache service afterward.Code:extension=php_curl.dll extension=php_openssl.dll
