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
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)
