In this tutorial, we will show you how to install Multiple PHP Versions on Ubuntu 18.04 LTS. For those of you who didn’t know, PHP (recursive acronym for PHP: Hypertext Preprocessor) is an open-source, popular general-purpose scripting language that is widely used and best suited for developing websites and web-based applications. It is a server-side scripting language that can be embedded in HTML.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Multiple PHP versions on a Ubuntu 18.04 (Bionic Beaver) server.
- A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).

root user. We recommend acting as a
non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Multiple PHP Versions on Ubuntu 18.04 LTS Bionic Beaver
Step 1. First, make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.
sudo apt-get update sudo apt-get upgrade sudo apt install apache2 libapache2-mod-fcgid
Step 2. Installing PHP.
First, add the PPA to your system:
sudo apt install python-software-properties sudo add-apt-repository ppa:ondrej/php
For this tutorial, we are using PHP 5.6 and PHP 7.2 to configure with the Apache webserver. To use the multiple PHP versions, we will use PHP FPM:
apt update sudo apt install php5.6 php5.6-fpm sudo apt install php7.2 php7.2-fpm
After installation, check the status of PHP services are running:
systemctl status php5.6-fpm systemctl status php7.2-fpm
Step 3. Apache Web Server Configuration.
First, create two directories on your server:
mkdir /var/www/php56 mkdir /var/www/php72
Next, create a test file named info.php with the content below. Save the file, then browse to it to see if PHP is working:
echo "<?php phpinfo(); ?>" > /var/www/php56/index.php echo "<?php phpinfo(); ?>" > /var/www/php72/index.php
Let’s start the creation of VirtualHost and edit in your favorite text editor:
Add the following content:
<VirtualHost *:80> ServerName php56.example.com DocumentRoot /var/www/php56 <Directory /var/www/php56> Options -Indexes +FollowSymLinks +MultiViews AllowOverride All Require all granted </Directory> <FilesMatch \.php$> # Apache 2.4.10+ can proxy to unix socket SetHandler "proxy:unix:/var/run/php/php5.6-fpm.sock|fcgi://localhost/" </FilesMatch> </VirtualHost>
Then, create a second VirtualHost configuration file to work with PHP 7.2:
Add the following content:
<VirtualHost *:80> ServerName php72.example.com DocumentRoot /var/www/php72 <Directory /var/www/php72> Options -Indexes +FollowSymLinks +MultiViews AllowOverride All Require all granted </Directory> <FilesMatch \.php$> SetHandler "proxy:unix:/var/run/php/php7.2-fpm.sock|fcgi://localhost/" </FilesMatch> </VirtualHost>
Create a symbolic link of config files to this directory or use the below command:
sudo a2ensite php56.example.com sudo a2ensite php72.example.com sudo a2enmod actions fastcgi alias proxy_fcgi
After making all the changes restart Apache to reload new settings changes:
systemctl restart apache2
Step 4. Test Multiple PHP Version.
Try to access it at php56.example.com shows the version PHP 5.6 and php72.example.com is showing PHP 7.2. If the PHP info page is rendered in your browser then everything looks good and you are ready to proceed further.
