Answer 2

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

Answer 3

Enter the following commands in the order shown:

apt-get -y update
add-apt-repository ppa:ondrej/php
apt-get -y update

apt-get -y install php5.6 php5.6-mcrypt php5.6-mbstring php5.6-curl php5.6-cli php5.6-mysql php5.6-gd php5.6-intl php5.6-xsl

Enter the following command to verify PHP 5.6 installed properly:

php -v

Following is a sample response that indicates PHP 5.6 is installed:

PHP 5.6.22-4+deb.sury.org~trusty+1 (cli)

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
