Installation

Ubuntu 16.04.2 LTS (Xenial) and Debian Stretch include PHP 7.0, and renamed many packages from "php5" to plain "php". In addition, some PHP modules are now in separate packages (xml, mbstring).

sudo apt-get install apache2 mysql-server php php-mysql libapache2-mod-php php-xml php-mbstring

Ubuntu Trusty, Debian Jessie and Raspbian (Jessie) include PHP 5, and use "php5" in most (but not all) packages.

sudo apt-get install apache2 mysql-server php5 php5-mysql libapache2-mod-php5
