Answer 1

CURLOPT_IPRESOLVE is available only >= CURL version 7.10.8 and your CURL version is 7.24.0. Need to update CURL in order for that CONSTANT to be available. And support for this constant is only available for PHP>=5.3

Yes, you may get latest curl. But you still have to install php-curl for php. you chould check whether you have or not have it.

php -i |grep curl
//this will be return in your linux command line.
/etc/php/7.1/cli/conf.d/20-curl.ini,
curl
