Do not add version, simply run sudo apt install php it would install latest. if you want add versions in apt install do as below

sudo add-apt-repository ppa:ondrej/php
sudo apt update

then you will be able to install whatever version you need to.

Currently the ondrej repositories does not support Ubuntu 14.04 as it reached end of life thus you cannot use them. You can either compile from source or upgrade your distribution.
