Solve the problem that PHP7.1 service cannot be found

There are several ways to solve this problem, we will introduce them one by one below.

Method 1: Manually activate PHP7.1

If you are using a Linux server, you can manually activate PHP 7.1 to solve this problem. You just need to run the following command in the terminal:

sudo a2dismod php5.6
sudo a2enmod php7.1
sudo service apache2 restart

This will disable PHP from the PHP5.6 module and enable the PHP7.1 module as well as restart the Apache service, which will make PHP7.1 work correctly with the Web server to interact.

Method 2: Reinstall PHP 7.1

If you still encounter problems after trying to manually activate PHP7.1, you can try to reinstall PHP7.1. Before reinstalling, you need to completely uninstall PHP7.1 and clear all related configuration data.
