Since pecl extension is compiled against PHP 5.6 in official FreeBSD repositories you’ll need to manually compile this PECL extension to have it included in PHP 7.0. Luckily for you process is really simple.

tar -xzvf geoip-1.1.1.tgz cd geoip-1.1.1/ ./configure
Finally, compile and install:
make make install
To have it loaded by your PHP-FPM (assuming you’re using it) include it in your php.ini configuration. I did it by creating /usr/local/etc/php/ext-99-geoip.ini file with following contents:
As extension is in PHP’s library PATH by default.
