How can PHP be used to generate email addresses based on user input and a constant domain?

To generate email addresses based on user input and a constant domain using PHP, you can concatenate the user input with the constant domain to form the email address. This can be done by retrieving the user input from a form submission and then combining it with the domain to create the email address. 

<?php
// Retrieve user input from a form submission
$userInput = $_POST['user_input'];

// Define the constant domain
$domain = 'example.com';

// Generate the email address by concatenating user input with the domain
$email = $userInput . '@' . $domain;

// Output the generated email address
echo $email;
?>
