How to me to add parameter to cURL?

[nkl90]

The command curl ifconfig.co print this:
2a01:7e00::f03c:91ff:fe18:68ff
That is, the system works through ipv6. And it is necessary for me that worked through ipv4.
I need to execute:
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
How can i do this? Perhaps do this config in global php.ini?
