What are the potential pitfalls of using POST instead of GET to pass parameters in a URL when updating data in a database using PHP?

Using POST instead of GET to pass parameters in a URL when updating data in a database using PHP can lead to security vulnerabilities, as POST parameters are not visible in the URL. To solve this issue, you can pass the parameters through a form submission using the POST method. 

<form method="post" action="update_data.php">
    <input type="hidden" name="id" value="123">
    <input type="text" name="new_data">
    <input type="submit" value="Update Data">
</form>
