How do I make a redirect in PHP?

To create a redirect in PHP, you can use the ‘header()‘ function. This function allows you to send a raw HTTP header to the client. To create a redirect, you need to send a ‘Location‘ header with the URL of the page you want to redirect the user to. Here is an example of how to create a redirect:

<?php
  // Redirect to the homepage
  header("Location: /index.php");
  exit;
?>

This will redirect the user to the homepage of the website. You can also use the ‘header()‘ function to specify the HTTP status code for the redirect. For example, to create a 301 permanent redirect, you can do the following:

<?php
  // Redirect to the homepage with a 301 status code
  header("HTTP/1.1 301 Moved Permanently");
  header("Location: /index.php");
  exit;
?>

Note that the ‘header()‘ the function must be called before any output is sent to the browser, so make sure to call it before any HTML or other content is printed.
