What are the best practices for naming form fields in PHP to avoid conflicts and ensure smooth data processing?

When naming form fields in PHP, it is important to use unique and descriptive names to avoid conflicts with other variables or form elements. To ensure smooth data processing, it is recommended to prefix form field names with a unique identifier or namespace. This helps to organize and differentiate form fields, especially when processing multiple forms on the same page.

<form action="process_form.php" method="post">
    <input type="text" name="contact_name" placeholder="Your Name">
    <input type="email" name="contact_email" placeholder="Your Email">
    <textarea name="contact_message" placeholder="Your Message"></textarea>
    <button type="submit">Submit</button>
</form>
