PHP (PHP: Hypertext Preprocessor) is one of the best options today to develop websites and web-based applications thanks to a wide set of integrated functions, that is why it is one of the most used and most popular languages ​​among developers. PHP offers versions 5.6, 7.0 and 8.0 while versions like 5.3, 5.4 and 5.5 are no longer supported..

For the Apache server we have the following options to install:
 sudo apt install php5.6 [PHP 5.6] sudo apt install php7.0 [PHP 7.0] sudo apt install php7.1 [PHP 7.1] sudo apt install php7.2 [PHP 7.2] sudo apt install php7.3 [PHP 7.3] sudo apt install php7.4 [PHP 7.4] sudo apt install php8.0 [PHP 8.0] 
Step 16

In the case of Nginx we have the following versions:
 sudo apt install php5.6-fpm [PHP 5.6] sudo apt install php7.0-fpm [PHP 7.0] sudo apt install php7.1-fpm [PHP 7.1] sudo apt install php7.2-fpm [PHP 7.2] sudo apt install php7.3-fpm [PHP 7.3] sudo apt install php7.4-fpm [PHP 7.4] sudo apt install php8.0-fpm [PHP 8.0] 
Step 17

In addition to this, it is possible to install modules based on the PHP destination:
 sudo apt install php5.6-cli php5.6-xml php5.6-mysql sudo apt install php7.0-cli php7.0-xml php7.0-mysql sudo apt install php7.1-cli php7.1-xml php7.1-mysql sudo apt install php7.2-cli php7.2-xml php7.2-mysql sudo apt install php7.3-cli php7.3-xml php7.3-mysql sudo apt install php7.3-cli php7.4-xml php7.4-mysql sudo apt install php7.3-cli php8.0-xml php8.0-mysq 

3. Configure default version of PHP in Ubuntu

 

Step 1

It is possible that we want to establish by default some of the used versions of PHP, for this we must execute the following syntax:
 sudo update-alternatives --set php / usr / bin / php # 
Step 2

To establish PHP 5.6 we execute:
 sudo update-alternatives --set php /usr/bin/php5.6 
Step 3

For PHP 7.1:
 sudo update-alternatives --set php /usr/bin/php7.1 
Step 4

For PHP 8.0 we use:
 sudo update-alternatives --set php /usr/bin/php8.0 
image

 

 

Step 5

It is possible to configure the version of PHP to use with the Apache web server, in this case it is required to deactivate the current version with the a2dismod command and then enable the desired version with the a2enmod command.

 

We uninstall the current 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 
image

 

Step 6

Then we enable the desired 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 
image

 

 

Step 7

Finally we restart the server with the following command:
 sudo systemctl restart apache2 
image

 

This is the simple and functional process to allow PHP to be installed in various versions on Ubuntu and then define the appropriate version to use..
