What is the best practice for passing and retrieving IDs in PHP for dynamic page creation?

When creating dynamic pages in PHP, it is best practice to pass and retrieve IDs through URL parameters. This allows for easy access to the ID within the PHP code and ensures that each page has a unique identifier. To retrieve the ID, you can use the $_GET superglobal array in PHP. 

// Passing ID in URL
<a href="dynamic_page.php?id=123">Link to Dynamic Page</a>

// Retrieving ID in PHP
$id = $_GET['id'];
echo "ID: " . $id;
