How can PHP be used to display the user's IP address on a webpage?

To display the user's IP address on a webpage using PHP, you can use the $_SERVER['REMOTE_ADDR'] variable, which contains the IP address of the user making the request to the server. You can then echo this variable within your HTML code to display the user's IP address on the webpage. 

<?php
$user_ip = $_SERVER['REMOTE_ADDR'];
echo "Your IP address is: $user_ip";
?>
