How can variables from a form be properly processed and included in a PHP email script for form submission?

To properly process variables from a form and include them in a PHP email script for form submission, you can use the $_POST superglobal array to retrieve the form data and then use the mail() function to send an email with the form content. Make sure to sanitize and validate the form data before including it in the email to prevent security vulnerabilities. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    
    // Sanitize and validate form data here
    
    $to = "recipient@example.com";
    $subject = "Form Submission";
    $body = "Name: $name\nEmail: $email\nMessage: $message";
    
    if (mail($to, $subject, $body)) {
        echo "Email sent successfully!";
    } else {
        echo "Failed to send email. Please try again.";
    }
}
?>
