Answer 1

TLS 1.2 is only supported since OpenSSL 1.0.1 (see the Major version releases section), you have to update your OpenSSL.

It is not necessary to set the CURLOPT_SSLVERSION option. The request involves a handshake which will apply the newest TLS version both server and client support. The server you request is using TLS 1.2, so your php_curl will use TLS 1.2 (by default) as well if your OpenSSL version is (or newer than) 1.0.1.
