How to remove re-sending a POST request?

Question

Browsers

Good to everyone!
Usually, when submitting a form and then reloading the page, the browser prompts you to submit the form again.
I have a search form on one page. The data is output and processed on another. When you reload or return to the data page, the browser prompts you to resubmit the form. Can this be bypassed somehow?

Answer 1

yes, you can, after submitting the form, redirect the user to the page url:

<?php
    if (!empty($_POST)) {
        // ......
       header('location:?');
    }
?>
<form method="post">
<input type="submit" name="submit">
</form>

Answer 2

Send asynchronous requests or do a redirect
