How can PHP developers ensure that the correct ID is passed to the next page via a link?

To ensure that the correct ID is passed to the next page via a link, PHP developers can include the ID as a query parameter in the URL of the link. This way, when the link is clicked, the ID will be passed as part of the URL and can be accessed on the next page using $_GET['id']. This ensures that the correct ID is carried over to the next page.

// Link to pass ID to next page
$id = 123; // ID value to pass
echo '<a href="nextpage.php?id=' . $id . '">Next Page</a>';
