How can you ensure that the page reloads automatically after writing to the file in PHP?

To ensure that the page reloads automatically after writing to a file in PHP, you can use the header() function to redirect the user back to the same page. After writing to the file, you can include a header redirect to the current page using the location header with a slight delay using the sleep() function to allow time for the write operation to complete.

<?php
// Write data to file
$file = 'data.txt';
$data = "Hello, World!";
file_put_contents($file, $data);

// Redirect back to the same page after a delay
header("Refresh: 2; url=".$_SERVER['REQUEST_URI']);
?>
