We can now install php 8.
Step 4 : Install different version of PHP
For apache you can now install any version
$ 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]
For Nginx
$ 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]In this way you can install any version. so finally we are installing PHP 8.0 with some basic important modules
sudo apt install php8.0Step 5 : Check installed versions of PHP
sudo update-alternatives --config phpOutput :
There are 3 choices for the alternative php (providing /usr/bin/php). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/php8.0 80 auto mode 1 /usr/bin/php7.0 70 manual mode 2 /usr/bin/php7.4 74 manual mode 3 /usr/bin/php8.0 80 manual mode Press <enter> to keep the current choice[*], or type selection number:
As we can see PHP 8.0 is installed and we have selected it as default by pressing 1.
Install modules for any version
Simply type the version you want to install then type tab to show available module for specific module.
