How can PHP be used to extract data from a link, such as an ID, for further processing?

To extract data from a link, such as an ID, in PHP, you can use the $_GET superglobal array. This array contains key-value pairs of parameters passed in the URL. You can access the ID by using $_GET['id'] where 'id' is the name of the parameter in the URL. Once you have extracted the ID, you can further process it as needed. 

// Assuming the URL is like: http://example.com/page.php?id=123

// Extract the ID from the URL
$id = $_GET['id'];

// Further processing of the extracted ID
echo "The ID extracted from the link is: " . $id;
