What are the different methods of redirecting to another script in PHP, and when should each method be used?

When redirecting to another script in PHP, there are several methods that can be used. The most common methods include using the header() function, the meta refresh tag, and JavaScript. The header() function is typically used for server-side redirects and is the preferred method for redirecting in PHP. The meta refresh tag is used for client-side redirects and involves adding an HTML meta tag to the page. JavaScript can also be used to redirect to another script by modifying the window location. Here is an example of how to redirect using the header() function in PHP:

<?php
// Redirect to another script using the header() function
header("Location: another_script.php");
exit;
?>
