What are the different methods of redirecting users in PHP, and when is each method most appropriate to use?

When redirecting users in PHP, there are several methods that can be used depending on the specific requirements of the application. The most common methods include using the header() function, the meta tag method, and the JavaScript method. The header() function is typically the preferred method for server-side redirects as it sends an HTTP header to the browser instructing it to redirect to a new location. The meta tag method involves using HTML meta tags to redirect users after a specified time interval. The JavaScript method involves using client-side JavaScript to redirect users to a new location. Here is an example of how to use the header() function to redirect users in PHP:

<?php
// Redirect to a new page
header("Location: https://www.example.com");
exit();
?>
