Run the following command to Install additional packages with PHP 7.4 on Debian 10 / 9

sudo apt-get install php7.4-{bcmath,bz2,intl,gd,mbstring,mysql,zip}

Similarly you can follow the same syntax to install your other packages with php 7.4

sudo apt-get install php7.4-xxx

Step 4: Installing Nginx on Debian 10 / 9

As you know that you will be required to Install a web server in order to gain access for using and testing php on your system. By default web server is Apache but Nginx provide more convenience so I will recommend to use Nginx on your Debian system. Firstly, disable the Apache server by running

sudo systemctl disable --now apache2

Now, Install the fpm extensions and nginx packages.

sudo apt-get install nginx php7.4-fpm

PHP fpm Configuration files are located in the directory /etc/php/7.4/fpm/

Make sure that the services are running properly.

$ systemctl status php7.4-fpm nginx
