How to Install Different PHP (5.6, 7.x and 8.0) Versions in Ubuntu

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.

Currently, there are three supported versions of PHP, i.e PHP 5.6, 7.0, and 8.0. Meaning PHP 5.3, 5.4, and 5.5 have all reached the end of life; they are no longer supported with security updates.

In this article, we will explain how to install all the supported versions of PHP in Ubuntu and its derivatives with the most requested PHP extensions for both Apache and Nginx web servers using an Ondřej Surý PPA. We will also explain how to set the default version of PHP to be used on the Ubuntu system.

Note that PHP 7.x is the supported stable version in the Ubuntu software repositories, you can confirm this by running the apt command below.

$ sudo apt show php OR $ sudo apt show php -a

------------ Set Default PHP Version 8.0 ------------ $ sudo update-alternatives --set php /usr/bin/php8.0

8. To set the PHP version that will work with the Apache web server, use the commands below. First, disable the current version with the a2dismod command and then enable the one you want with the a2enmod command.

----------- Disable PHP Version ----------- $ sudo a2dismod php5.6 $ sudo a2dismod php7.0 $ sudo a2dismod php7.1 $ sudo a2dismod php7.2 $ sudo a2dismod php7.3 $ sudo a2dismod php7.4 $ sudo a2dismod php8.0 ----------- Enable PHP Version ----------- $ sudo a2enmod php5.6 $ sudo a2enmod php7.1 $ sudo a2enmod php7.2 $ sudo a2enmod php7.3 $ sudo a2enmod php7.4 $ sudo a2enmod php8.0 ----------- Restart Apache Server ----------- $ sudo systemctl restart apache2

9. After switching from one version to another, you can find your PHP configuration file, by running the command below.

------------ For PHP 5.6 ------------ $ sudo update-alternatives --set php /usr/bin/php5.6 $ php -i | grep "Loaded Configuration File" ------------ For PHP 7.0 ------------ $ sudo update-alternatives --set php /usr/bin/php7.0 $ php -i | grep "Loaded Configuration File" ------------ For PHP 7.1 ------------ $ sudo update-alternatives --set php /usr/bin/php7.1 $ php -i | grep "Loaded Configuration File" ------------ For PHP 7.2 ------------ $ sudo update-alternatives --set php /usr/bin/php7.2 $ php -i | grep "Loaded Configuration File" ------------ For PHP 7.3 ------------ $ sudo update-alternatives --set php /usr/bin/php7.3 $ php -i | grep "Loaded Configuration File" ------------ For PHP 7.4 ------------ $ sudo update-alternatives --set php /usr/bin/php7.4 $ php -i | grep "Loaded Configuration File" ------------ For PHP 8.0 ------------ $ sudo update-alternatives --set php /usr/bin/php8.0 $ php -i | grep "Loaded Configuration File"

How to Change Default PHP Version on Ubuntu

On your system, if you have installed multiple versions of PHP like PHP 8.2, PHP 7.4 and PHP 5.6. Currently, PHP 7.4 is the default version set for Apache and the command line interface (CLI). Maybe you have any other PHP versions installed on your system. Only one PHP version can be set as default at any time.

This tutorial will help you to change the default PHP version for CLI and Apache webserver. This can be achieved with a few sets of commands.

Switch to PHP 8.2

Before switching to PHP 8.2, you have to deactivate the previously activated Apache module. The following commands will deactivate the already activated Apache module and then activate PHP 8.2 Apache module. Then the next commands will set PHP 8.2 as the default version for the command line interface (CLI).

sudo a2dismod php* sudo a2enmod php8.2 sudo systemctl restart apache2 

sudo update-alternatives --set php /usr/bin/php8.2 sudo update-alternatives --set phar /usr/bin/phar8.2 sudo update-alternatives --set phar.phar /usr/bin/phar.phar8.2 sudo update-alternatives --set phpize /usr/bin/phpize8.2 sudo update-alternatives --set php-config /usr/bin/php-config8.2 

Note: The phpize8.2 and php-config8.2 command is available in php8.2-dev package. This is more useful for compiling PHP modules using pecl.

If you want a different version (eg: PHP 8.1 or PHP 8.0) to be configured as default, just replace 8.2 with the required version.

Switch to PHP 7.4

Similarly, if you need to configure PHP 7.4 as the default version in your system. The following set of commands will change the default PHP to 7.4 for the Apache web server and command line interface.

sudo a2dismod php* sudo a2enmod php7.4 sudo systemctl restart apache2 

sudo update-alternatives --set php /usr/bin/php7.4 sudo update-alternatives --set phar /usr/bin/phar7.4 sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.4 sudo update-alternatives --set phpize /usr/bin/phpize7.4 sudo update-alternatives --set php-config /usr/bin/php-config7.4 

Note – The phpize7.4 and php-config7.4 command is available in php7.4-dev package. This is more useful for compiling PHP modules using pecl.

Switch to PHP 5.6

PHP 5.6 is an outdated version. So if you have an application that required PHP 5.6, consider them to upgrade to last PHP version. The following set of commands will change the default PHP to 5.6 for the Apache web server and command line interface.

sudo a2dismod php* sudo a2enmod php5.6 sudo systemctl restart apache2 

sudo update-alternatives --set php /usr/bin/php5.6 sudo update-alternatives --set phar /usr/bin/phar5.6 sudo update-alternatives --set phar.phar /usr/bin/phar.phar5.6 sudo update-alternatives --set phpize /usr/bin/phpize5.6 sudo update-alternatives --set php-config /usr/bin/php-config5.6 

Note: The phpize5.6 and php-config5.6 command is available in php5.6-dev package. This is more useful for compiling PHP modules using pecl.
