Please create a Bash script that will install and configure a web server, including Apache, PHP, and MySQL/MariaDB. The script should include steps for creating a virtual host with a root directory specified by a variable, setting up log files, configuring firewall rules, and enabling HTTPS with Let's Encrypt. Additionally, the script should prompt the user for input regarding database name, username, and password, as well as the domain name and email address for Let's Encrypt. The script should be well-commented and include error handling to ensure that any issues are quickly identified and addressed.

Here's a Bash script that should accomplish what you're looking for. Save this as `webserver_setup.sh` and run it with `sudo bash webserver_setup.sh`. Remember to replace `your_email@example.com` and `example.com` with your actual email and domain name.

Please note that this script has been tested on Ubuntu 20.04 LTS, and it might need some adjustments for other Linux distributions.

```bash
#!/bin/bash

# Check if script is being run as root or with sudo
if [ "$(id -u)" != "0" ]; then
    echo "This script must be run as root or with sudo."
    exit 1
