What is the best way to display the URL that a user has entered in PHP?

To display the URL that a user has entered in PHP, you can use the $_SERVER['REQUEST_URI'] variable, which contains the URL path that was requested by the user. You can then echo this variable to display the URL on the webpage.

<?php
  $url = $_SERVER['REQUEST_URI'];
  echo "The URL entered by the user is: " . $url;
?>
