security - PHP 7.0.8 missing Curl constant -

i installed php 7.0.8 version here: http://rpms.remirepo.net/wizard/

from phpinfo:

php version 7.0.8 

then installed latest version curl, show in phpinfo:

curl information    7.49.1 

this page shows new curl option has been added 7.0.7:

i.e. curlopt_pinnedpublickey 

http://php.net/manual/en/function.curl-setopt.php

but when run code

echo curlopt_pinnedpublickey 

its return string, not integer....

or using in curl:

        curl_setopt($ch, curlopt_pinnedpublickey, "sha256//teyzgg/8dvpuksaescb3tsvlehby6w9q63txhoif0tg="); 

it doesn't work either...

===== edit: add php info

and here phpinfo: https://www.dropbox.com/s/9xdmx9i67rabcql/phpinfo%28%29.html?dl=0
