This installation was tested on Ubuntu 15.01 but could be used for a debian production server.

SuPhp has not been maintained for a few years now, so it is no longer in the repositories of recent distributions, and it has become difficult to compile it on a 4.x kernel (which is my case, since my transition to Ubuntu 15.10).

Note: the package is still available on Ubuntu 14.01LTS.

2- PHP Compilation

First, we create a symbolic link for a library that might be potentially missing during the compilation:

sudo ln -s /usr/include/x86_64-linux-gnu/gmp.h /usr/include/gmp.h

We retrieve the PHP source code:

sudo wget -O php-5.6.16.tar.gz && tar xzvf php-5.6.16.tar.gz && cd php-5.6.16

Then we compile:

sudo ./configure --prefix=/usr/local/php --with-apxs2=/usr/bin/apxs2  --with-config-file-path=/usr/local/php/conf --with-config-file-scan-dir=/usr/local/php/conf.d --enable-debug --with-openssl --with-kerberos --with-zlib --enable-calendar --with-curl  --with-enchant --enable-exif --enable-ftp --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-vpx-dir=/usr --with-freetype-dir=/usr  --enable-exif --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-gmp --with-mhash --enable-intl --enable-mbstring --with-mcrypt --with-mysql --with-mysqli --enable-pcntl --with-pdo-mysql --with-pdo-pgsql --with-pgsql --with-pspell --with-libedit --with-readline --enable-shmop  --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvshm --with-xsl --enable-zip --with-pear --enable-zend-signals --enable-maintainer-zts --enable-bcmath  && sudo make && sudo make install

3- Apache configuration:
We reference our directory where PHP is located, in the apache2 configuration file /etc/apache2/apache2.conf

sudo vi /etc/apache2/apache2.conf

ScriptAlias /php5.6.16/ "/usr/local/php/bin/"
<Directory "/usr/local/php/bin/">
AllowOverride All
Options None
Order allow,deny
Allow from all

We then proceed to configure our virtual host with the following directives:

Action php-script '/php5.6.16/php-cgi-5.6.16'
AddHandler php-script .php
PHPIniDir "/var/www/ATLV/"

This gives us a configuration as follows:

<VirtualHost *:80>
Options FollowSymLinks
DirectoryIndex app_dev.php
DocumentRoot /var/www/ATLV/web

Action php-script '/php5.6.16/php-cgi-5.6.16'
AddHandler php-script .php
PHPIniDir "/var/www/ATLV/"
<Directory /var/www/ATLV/web>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
DirectoryIndex app_dev.php

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

We just have to enable the actions mod:

a2enmod actions

And to restart apache2:

service apache2 restart

And voila:
