Complementing answers and publishing what worked for me:
1 followed this guide in order to install lamp https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-16-04 (The third step is needed only for installing the mongo client)
2 $ sudo apt-get install php7.0-dev
3 $ sudo pecl install mongodb
4 $ sudo nano /etc/php/7.0/apache2/php.ini
Add the following line in the file:
extension = mongo.so;
(You might need to specify the exact location of the file. In my case the file was in /usr/lib/php/20151012/mongodb.so.)
And thats all for installing just the mongo client for php 7.0
