What is the purpose of using a form in PHP to create a button for database updates?

When updating a database in PHP, using a form to create a button allows users to trigger the update action. This button can be styled and positioned as needed on the webpage, providing a clear and intuitive way for users to interact with the database. Additionally, by wrapping the update action within a form, you can easily handle any necessary data validation and security measures before executing the update query.

<form method="post" action="update.php">
    <input type="submit" name="update_button" value="Update Database">
</form>
