How to upgrade php 5.5.9 to 7.0
Hello, i'm using Ubuntu 14.04 and PHP 5.5.9, but i need to upgrade PHP to a new version, 7.0.
What's i need to do? I think that's:
1º - Add PPA Repository : "add-apt-repository ppa:ondrej/php"
2º - Update : "apt-get update"
3º - Upgrade: "apt-get upgrade"
Would it be this?
