Installing PHP 7 on Debian 8 connection problem?

Question

PHP

Good afternoon, I installed PHP 7.1 - dev on Debian 8.
SSH using the php -v command gives exactly the version I need, but the problem is that the site for deriving the function shows the old version (5.6. *)
Could there be a problem in cgi-bin?
The contents of the file /cgi-bin/php : #!/usr/bin/php-cgi
PHP uploaded to /root/php7
Everything was done according to the manual from here anikin.pw/all/asborka-php-7-na-debian-8-jessie
