What are the advantages of using a single form for multiple input fields in PHP, compared to separate forms for each field?

When using a single form for multiple input fields in PHP, you can simplify your code by handling all the form data submission and processing in one place. This approach can also improve user experience by presenting a cleaner and more organized interface. Additionally, it can reduce the amount of code duplication and make it easier to maintain and update your form in the future.

<form action="process_form.php" method="post">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name"><br>
    
    <label for="email">Email:</label>
    <input type="email" id="email" name="email"><br>
    
    <label for="message">Message:</label>
    <textarea id="message" name="message"></textarea><br>
    
    <input type="submit" value="Submit">
</form>
