How can PHP be used to extract the source code of the current page?

To extract the source code of the current page using PHP, you can use the `file_get_contents()` function to read the contents of the current page's URL. This function will retrieve the HTML source code of the page and store it in a variable for further processing or display. 

<?php
$current_page_source = file_get_contents("http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
echo $current_page_source;
?>
