In PHP form handling, what are the benefits of omitting the action attribute altogether and relying on the default behavior of the current page as the form action?

When omitting the action attribute in a form, the default behavior is for the form to submit to the current page. This can be beneficial as it simplifies the code by removing the need to specify the action URL explicitly. It also allows for more flexibility in case the URL of the current page changes, as the form will automatically submit to the updated URL. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Form submission logic here
}
?>

<form method="post">
    <!-- Form fields go here -->
    <button type="submit">Submit</button>
</form>
