Is it necessary to write all PHP code in a separate file when transferring form inputs to an HTML email?

When transferring form inputs to an HTML email, it is not necessary to write all PHP code in a separate file. You can include the PHP code directly within the HTML file where the form is submitted. This allows you to easily access the form inputs and process them within the same file without the need for additional files. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    $to = "recipient@example.com";
    $subject = "New Form Submission";
    $message = "Name: $name\nEmail: $email";
    
    mail($to, $subject, $message);
    
    echo "Email sent successfully!";
}
?>
