$ sudo a2dismod php5
$ sudo cp /etc/apache2/mods-available/php5.conf /etc/apache2/mods-enabled/php7.conf
$ sudo service apache2 restart

Will this install the stable version of PHP7? I see alot of dev packages...

Anyone tested on Ubuntu Server 14.04.3?

http://pear.php.net/install-pear-nozlib.phar is throwing a 404 error ?!?
anyone got it working ?

work on Raspbian GNU/Linux 8.0 (jessie), but slower than PHP Version 5.6.14-0+deb8u1

So this is what ended up working for me on Ubuntu 14.04 with Nginx:
sudo service nginx stop
sudo apt-get purge php5-*
sudo add-apt-repository ppa:ondrej/php-7.0
sudo apt-get update
sudo apt-get install php7.0 php7.0-common php7.0-cgi php7.0-fpm php7.0-mysql

Then edit your Nginx config file:
sudo nano /etc/nginx/sites-available/thedomainnamegoeshere.com
location ~ .php$ {
include fastcgi_params;
fastcgi_keep_conn on;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}

Then restart Nginx:
sudo service nginx start

Add check for root-prvilege

if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

How can i compile it withj mssql drivers/dblib? --with-mssql doesnt work?

For Apache2, add to @jacobschweitzer method :
sudo apt-get install libapache2-mod-php7.0

Thanks @ram-you

Script is falling for me

Please add root-permission check like @akeinhell stated 7 days ago:

if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

Also, add the 'make' package to 'apt-get install' list of packages; I just installed a fresh 14.04 server, and that package was missing :)

thanks @akeinhell, I've added it

thanks @hvanmegen, I've added the make to 'apt-get install'.
