In what scenarios would using echo $_GET["seite"] be useful, and what output would it provide based on the URL parameter?

Using `echo $_GET["seite"]` would be useful when you want to retrieve a value from the URL parameter named "seite" and display it on the webpage. This can be helpful when you need to pass information through the URL, such as page numbers, user IDs, or any other dynamic data. The output provided by `echo $_GET["seite"]` would be the value of the "seite" parameter in the URL. 

<?php
// Assuming the URL is http://example.com/page.php?seite=2
echo $_GET["seite"]; // This will output: 2
?>
