What are the advantages and disadvantages of using meta-equiv tags versus JavaScript for reloading a page to clear post data in PHP?

When submitting a form in PHP, the data is often stored in the POST array. To clear this data and prevent resubmission of the form when refreshing the page, you can either use meta-equiv tags in the HTML header or JavaScript to reload the page. Using meta-equiv tags is a simpler solution as it requires less code, but it may not work consistently across all browsers. On the other hand, using JavaScript gives you more control and flexibility, but it adds complexity to the code. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data

    // Redirect to clear POST data
    echo '<meta http-equiv="refresh" content="0;url=your_page.php">';
    exit;
}
?>
