You are seeing the versions of two different pieces of PHP.

The first output is for the curl module. PHP's curl interface uses the curl library provided by the OS, which then uses the OpenSSL library it is linked against, in this case 1.0.1f.

Then, PHP has a direct OpenSSL interface, which is linked against version 1.1.0g.

If you want curl to use a newer OpenSSL version, you need to upgrade your curl library, and make sure PHP's curl module uses the newer library.
