What are the best practices for naming form fields in PHP to ensure a database-friendly structure without the need for transposing arrays?

When naming form fields in PHP, it is best practice to use lowercase letters, underscores for spaces, and be descriptive yet concise. This ensures a database-friendly structure without the need for transposing arrays. By following these guidelines, you can easily map form fields to database columns without any additional manipulation.

<form action="process_form.php" method="post">
    <input type="text" name="first_name" placeholder="First Name">
    <input type="text" name="last_name" placeholder="Last Name">
    <input type="email" name="email_address" placeholder="Email Address">

</form>
