Question

Switch one-click-LAMP droplet to PHP v7.2

I created the droplet using the “Create LAMP droplet” button on https://marketplace.digitalocean.com/apps/lamp#getting-started. My website is old, was created with PHP7.2, and delivers a blank screen with my new droplet. I assume that it will not run on PHP8. What do I need to do to get the droplet using PHP7.2?

Heya,

In order to use PHP 7.2, you’ll need to install it and then switch to that PHP version so that Apache knows which one to use.

PHP 7.2 is not included in the default Ubuntu repositories for newer versions of Ubuntu. You need to add the repository maintained by Ondřej Surý, which includes PHP 7.2.

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

Now you can install PHP 7.2 and the necessary modules.

sudo apt-get install php7.2 php7.2-cli php7.2-fpm php7.2-mysql php7.2-xml php7.2-curl php7.2-gd php7.2-mbstring php7.2-zip php7.2-soap php7.2-intl

You need to disable the current PHP module for Apache and enable the PHP 7.2 module.

sudo a2dismod php8.0
sudo a2enmod php7.2

Finally, restart the Apache server to apply the changes.

sudo systemctl restart apache2
