问题
I installed a new local server, when I installed php5 package with apt-get install php5 it got the version 5.6.
My production server is still with php 5.5 and I would like to upgrade it to php 5.6 like in my dev environment.
Can I do it easily using apt-get ? tell to apt-get to switch to the branch 5.6 ?
Thx

To upgrade to a newer version of PHP 5.6 on Ubuntu 14.04, you can use Ondřej Surý's PPA. He is one of the Debian maintainers of the php5 package. To add the PPA and upgrade your packages, run:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php5-5.6
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php5

I know that it's a little late to answer this question , but for anyone like me who is confused when upgrading php , I should say please note that before installing new version of php remove it completely from your system, even remove config files and extensions, It caused me so many errors and problems.
sudo apt-get purge php.*
sudo rm -rf /etc/php5
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php5-5.6
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php5
