Introduction to Installing Multiple PHP Versions with Apache on Ubuntu 20.04
Installing Multiple PHP Versions with Apache on Ubuntu 20.04
If you’re a web developer or administrator, you may have encountered situations where you need to work with different versions of PHP for different projects. Fortunately, it’s possible to install multiple PHP versions on your Ubuntu 20.04 server and configure Apache to use the desired version for each project. In this article, we’ll walk you through the process of installing and configuring multiple PHP versions with Apache on Ubuntu 20.04.
Before we dive into the installation process, let’s briefly discuss why you might need multiple PHP versions. Different PHP versions may be required for compatibility reasons, as some projects may rely on specific PHP features or functions that are only available in certain versions. Additionally, you may want to test your code against different PHP versions to ensure its compatibility and performance across different environments.
To get started, you’ll need to have Apache and PHP already installed on your Ubuntu 20.04 server. If you haven’t done so, you can install Apache and PHP by running the following commands:
“`
sudo apt update
sudo apt install apache2
sudo apt install php
“`
Once you have Apache and PHP installed, you can proceed with installing multiple PHP versions. The first step is to add the ondrej/php PPA repository, which provides the latest PHP versions for Ubuntu. Run the following commands to add the repository:
“`
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update
“`
After adding the repository, you can install the desired PHP versions using the apt package manager. For example, to install PHP 7.4 and PHP 8.0, run the following commands:
“`
sudo apt install php7.4
sudo apt install php8.0
“`
Once the installation is complete, you’ll have multiple PHP versions available on your server. However, Apache will still be configured to use the default PHP version. To configure Apache to use a specific PHP version for a particular project, you’ll need to create a new virtual host configuration file.
Navigate to the Apache configuration directory by running the following command:
“`
cd /etc/apache2/sites-available
“`
Create a new virtual host configuration file for your project using a text editor. For example, to create a configuration file for a project called “myproject”, run the following command:
“`
sudo nano myproject.conf
“`
In the configuration file, add the following lines to specify the PHP version you want to use:
“`
ServerName myproject.com
DocumentRoot /var/www/myproject
SetHandler “proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost/”
“`
Replace “myproject.com” with your project’s domain or hostname, and “/var/www/myproject” with the actual path to your project’s root directory. Additionally, make sure to specify the correct PHP version in the “SetHandler” line.
Save the configuration file and exit the text editor. Next, enable the virtual host by creating a symbolic link in the “sites-enabled” directory:
“`
sudo ln -s /etc/apache2/sites-available/myproject.conf /etc/apache2/sites-enabled/
“`
Finally, restart Apache for the changes to take effect:
“`
sudo systemctl restart apache2
“`
Now, Apache will use the specified PHP version for the “myproject” virtual host. You can repeat the above steps to create virtual host configuration files for other projects, each using a different PHP version.
In conclusion, installing multiple PHP versions with Apache on Ubuntu 20.04 allows you to work with different PHP versions for different projects. By following the steps outlined in this article, you can easily install and configure multiple PHP versions on your server, ensuring compatibility and flexibility in your web development projects.

First things first, let’s make sure you have Apache installed on your server. Open up your terminal and type the following command:
“`
sudo apt update
sudo apt install apache2
“`
Once Apache is installed, you’ll need to install the necessary PHP versions. Ubuntu 20.04 comes with PHP 7.4 by default, but you can install additional versions using the ondrej/php PPA. To add the PPA, run the following commands:
“`
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update
“`
Now that the PPA is added, you can install additional PHP versions. For example, if you want to install PHP 7.3 and PHP 8.0, you can run the following commands:
“`
sudo apt install php7.3
sudo apt install php8.0
“`
Once the PHP versions are installed, you’ll need to configure Apache to work with them. Apache uses a module called `libapache2-mod-php` to integrate with PHP. By default, this module is configured to work with the latest installed PHP version. To change this behavior, you’ll need to enable the `php7.3` and `php8.0` modules.
To enable the `php7.3` module, run the following command:
“`
sudo a2enmod php7.3
“`
To enable the `php8.0` module, run the following command:
“`
sudo a2enmod php8.0
“`
Once the modules are enabled, you’ll need to restart Apache for the changes to take effect:
“`
sudo systemctl restart apache2
“`
Now, Apache is configured to work with multiple PHP versions. However, you’ll need to specify which PHP version to use for each website. To do this, you’ll need to create a virtual host configuration file for each website.
Navigate to the Apache configuration directory:
“`
cd /etc/apache2/sites-available
“`
Create a new virtual host configuration file for your website. For example, if your website is called `example.com`, you can run the following command:
“`
sudo nano example.com.conf
“`
In the virtual host configuration file, add the following lines to specify the PHP version:
“`
ServerName example.com
DocumentRoot /var/www/example.com
SetHandler “proxy:unix:/run/php/php7.3-fpm.sock|fcgi://localhost/”
“`
Save the file and exit the text editor. Repeat this process for each website, replacing `example.com` with the appropriate domain name and `php7.3` with the desired PHP version.
Once you’ve created the virtual host configuration files, you’ll need to enable them. Run the following command for each configuration file:
“`
sudo a2ensite example.com.conf
“`
Finally, restart Apache for the changes to take effect:
“`
sudo systemctl restart apache2
“`
And that’s it! You’ve successfully installed multiple PHP versions on your Ubuntu 20.04 server and configured Apache to work with them. Now you can test your code or run multiple websites with different PHP versions. Happy coding!

Navigate to the Apache configuration directory by running:
“`
cd /etc/apache2/sites-available
“`
Create a new virtual host configuration file for PHP 7.4:
“`
sudo cp 000-default.conf php74.conf
sudo nano php74.conf
“`
In the configuration file, update the `DocumentRoot` and `Directory` directives to point to the directory of your PHP 7.4 project. Save the file and exit the editor.
Repeat the process for PHP 8.0:
“`
sudo cp 000-default.conf php80.conf
sudo nano php80.conf
“`
Update the `DocumentRoot` and `Directory` directives to point to the directory of your PHP 8.0 project. Save the file and exit the editor.
Next, enable the virtual host configurations by running:
“`
sudo a2ensite php74.conf
sudo a2ensite php80.conf
“`
Finally, restart Apache once again:
“`
sudo systemctl restart apache2
“`
You can now access your PHP 7.4 project by visiting the domain or IP address associated with the `php74.conf` virtual host. Similarly, you can access your PHP 8.0 project using the `php80.conf` virtual host.
In conclusion, managing multiple PHP versions with Apache on Ubuntu 20.04 is a straightforward process. By following the steps outlined in this article, you can easily install and configure multiple PHP versions, allowing you to work with different PHP projects on the same server.
Troubleshooting Common Issues when Installing Multiple PHP Versions on Ubuntu 20.04
Installing Multiple PHP Versions with Apache on Ubuntu 20.04
So, you’ve decided to install multiple PHP versions on your Ubuntu 20.04 server. It’s a great choice, as it allows you to test your applications with different PHP versions and ensure compatibility. However, like any installation process, there can be some common issues that you might encounter. In this article, we will troubleshoot these issues and guide you through the process smoothly.
Firstly, before we dive into troubleshooting, let’s quickly go over the steps to install multiple PHP versions on Ubuntu 20.04. The process involves adding a PPA (Personal Package Archive) repository that provides different PHP versions, updating the package list, and finally installing the desired PHP versions.
Now, let’s address the first common issue you might face – conflicting dependencies. When you try to install multiple PHP versions, you might encounter dependency conflicts between different PHP packages. This can result in errors and prevent the installation from completing successfully. To resolve this, you can use the `aptitude` command, which is a more advanced package manager. It can help you resolve conflicts by suggesting alternative solutions or allowing you to choose specific packages to install.
Another issue you might come across is the inability to switch between PHP versions. After installing multiple PHP versions, you might find that Apache is still using the default PHP version. This can happen because Apache is not aware of the newly installed PHP versions. To fix this, you need to configure Apache to recognize and use the desired PHP version. This can be done by creating separate Apache configuration files for each PHP version and enabling the appropriate configuration file using the `a2enconf` command.
Next, let’s talk about the issue of missing PHP extensions. When you install additional PHP versions, they might not come with all the extensions that your applications require. This can lead to errors when running your applications. To resolve this, you can use the `phpenmod` command to enable the required PHP extensions for each PHP version. Additionally, you can use the `php-config` command to check the available extensions and their status.
Furthermore, you might encounter issues with PHP-FPM (FastCGI Process Manager) when installing multiple PHP versions. PHP-FPM is a popular alternative to mod_php, as it provides better performance and resource management. However, when using multiple PHP versions, you need to configure PHP-FPM to work with each version separately. This involves creating separate PHP-FPM pool configurations for each PHP version and updating the Apache virtual host configuration to use the appropriate PHP-FPM pool.
Lastly, let’s address the issue of conflicting PHP configuration files. Each PHP version comes with its own configuration files, and conflicts can arise when multiple versions are installed. This can result in unexpected behavior or errors when running your applications. To avoid this, you can create separate directories for each PHP version’s configuration files and update the PHP-FPM and Apache configurations accordingly.
In conclusion, installing multiple PHP versions on Ubuntu 20.04 can be a powerful tool for testing and ensuring compatibility. However, it’s important to be aware of the common issues that can arise during the installation process. By troubleshooting conflicts, configuring Apache and PHP-FPM correctly, enabling required extensions, and managing configuration files, you can successfully install and use multiple PHP versions on your Ubuntu 20.04 server. Happy coding!
Best Practices for Installing Multiple PHP Versions with Apache on Ubuntu 20.04

However, you may need to install additional PHP versions to meet your specific requirements. Fortunately, Ubuntu’s package manager, apt, makes it easy to install and manage multiple PHP versions.
To get started, open a terminal and update your package lists by running the following command:
“`
sudo apt update
“`
Once the package lists are updated, you can proceed with installing the desired PHP versions. Ubuntu provides separate packages for each PHP version, so you can install them side by side. For example, to install PHP 7.3 and PHP 7.2, you can run the following commands:
“`
sudo apt install php7.3
sudo apt install php7.2
“`
After the installation is complete, you’ll have multiple PHP versions installed on your system. However, Apache will only use the default PHP version. To configure Apache to use a specific PHP version, you’ll need to enable the corresponding PHP module.
To enable a PHP module, use the `a2enmod` command followed by the module name. For example, to enable PHP 7.3, run the following command:
“`
sudo a2enmod php7.3
“`
Once the module is enabled, you’ll need to restart Apache for the changes to take effect:
“`
sudo systemctl restart apache2
“`
Now, Apache will use PHP 7.3 instead of the default PHP version. To switch to a different PHP version, simply disable the current PHP module and enable the desired one. For example, to switch to PHP 7.2, run the following commands:
“`
sudo a2dismod php7.3
sudo a2enmod php7.2
sudo systemctl restart apache2
“`
With these steps, you can easily switch between different PHP versions on your Ubuntu 20.04 server. However, it’s important to note that each PHP version may require different extensions or configurations.

“`
Similarly, you can install other extensions as per your requirements.
In addition to installing extensions, you may also need to modify the PHP configuration files for each version. The configuration files are located in the `/etc/php/{version}/apache2/` directory. You can edit these files using a text editor of your choice.
In conclusion, installing multiple PHP versions with Apache on Ubuntu 20.04 is a straightforward process. By following the best practices outlined in this article, you can easily switch between different PHP versions and ensure compatibility with your applications. Remember to install the necessary extensions and modify the configuration files as needed. Happy coding!
Exploring Advanced Techniques for Managing Multiple PHP Versions on Ubuntu 20.04
Installing Multiple PHP Versions with Apache on Ubuntu 20.04
If you’re a developer working with PHP, you may find yourself needing to work with multiple PHP versions on your Ubuntu 20.04 system. Fortunately, it’s possible to install and manage multiple PHP versions with Apache on Ubuntu 20.04, allowing you to easily switch between different PHP versions for different projects or testing purposes. In this article, we’ll explore the advanced techniques for managing multiple PHP versions on Ubuntu 20.04.
Before we dive into the installation process, it’s important to note that Ubuntu 20.04 comes with PHP 7.4 installed by default. However, you may need to work with older versions of PHP or even newer versions that are not available in the default repositories. That’s where the ability to install multiple PHP versions becomes crucial.
To get started, you’ll need to add a Personal Package Archive (PPA) that provides the PHP versions you want to install. One popular PPA is OndÅ™ej Surý’s PPA, which provides a wide range of PHP versions for Ubuntu. To add this PPA, open a terminal and run the following commands:

This command will install PHP 7.2, 7.3, and 7.4 on your Ubuntu 20.04 system. You can replace these versions with any other versions available in the PPA.
After the installation is complete, you’ll need to configure Apache to work with these PHP versions. Apache uses a module called `libapache2-mod-php` to integrate PHP with the web server. By default, this module is configured to use the latest installed PHP version.
To switch between PHP versions, you’ll need to disable the current version and enable the desired version. You can do this by running the following commands:
“`
sudo a2dismod php7.4
sudo a2enmod php7.3
sudo systemctl restart apache2
“`
In this example, we’re disabling PHP 7.4 and enabling PHP 7.3. After restarting Apache, it will start using PHP 7.3 instead of 7.4.
To verify that the PHP version has been switched successfully, you can create a PHP info file. Create a new file called `info.php` in your web server’s document root directory with the following content:
“`php
“`
Save the file and access it through your web browser. You should see the PHP information page, which will display the currently active PHP version.
By following these steps, you can easily switch between multiple PHP versions on your Ubuntu 20.04 system. This flexibility allows you to work with different PHP versions for different projects or test compatibility with older versions.
In conclusion, managing multiple PHP versions on Ubuntu 20.04 is a straightforward process that can greatly enhance your development workflow. By adding a PPA, installing the desired PHP versions, and configuring Apache, you can seamlessly switch between different PHP versions and ensure compatibility with various projects. So go ahead and experiment with different PHP versions to optimize your development environment.
Conclusion
In conclusion, installing multiple PHP versions with Apache on Ubuntu 20.04 allows users to run different PHP applications with different PHP versions on the same server. This can be achieved by using the PHP version manager (phpbrew) or by compiling and installing multiple PHP versions manually. By following the appropriate steps and configurations, users can successfully set up and manage multiple PHP versions with Apache on Ubuntu 20.04.
