How can a PHP script extract and display a value from a URL?

To extract and display a value from a URL in a PHP script, you can use the $_GET superglobal array to access the parameters passed in the URL. You can then retrieve the specific value by specifying the key associated with the parameter in the URL. Finally, you can display the value on the webpage using echo or print. 

<?php
// Assuming the URL is http://example.com/page.php?id=123
$value = $_GET['id']; // Extract the value of 'id' parameter from the URL
echo "The value extracted from the URL is: " . $value; // Display the extracted value on the webpage
?>
