A build script that I use for Vagrant/Parallels to install php7 (and the rest of the LAMP stack) on ubuntu 14.04 for webdev server.

build.sh

#!/usr/bin/env bash

#PHP7/Mysql/Apache/Composer/GIT installer script used for parallels vagrant/ubuntu14.04

#Grab Curl
sudo apt-get -y install curl

# create project folder
sudo mkdir "/var/www/html/${PROJECTFOLDER}"

apt-get install -y apache2

#install php7

# install mysql and give password to installer

sudo apt-get -y install mysql-server

# setup hosts file
VHOST=$(cat <<EOF

    DocumentRoot "/var/www/html/${PROJECTFOLDER}/public"
    <Directory "/var/www/html/${PROJECTFOLDER}">
        AllowOverride All

echo "${VHOST}" > /etc/apache2/sites-available/000-default.conf

# enable mod_rewrite
sudo a2enmod rewrite

# restart apache
service apache2 restart

# install git
sudo apt-get install -y git

# install Composer
curl -s https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

This script is intended for non public (off net) development, and I usually run it as 'sudo'.

Enjoy.
