What steps should be taken to ensure that the ID of a news article is properly accepted and processed when linking to it from different pages?

When linking to a news article from different pages, it is important to ensure that the ID of the article is properly accepted and processed to avoid any errors. One way to do this is to use URL parameters to pass the ID value and retrieve it on the linked page. This can be done by appending the ID to the URL as a query parameter and then extracting it using PHP's $_GET superglobal array. 

// Link to the news article with the ID parameter
<a href="article.php?id=123">Read More</a>

// Retrieve the ID parameter on the linked page
$id = $_GET['id'];

// Use the ID to fetch the article content from the database
// Example query: SELECT * FROM articles WHERE id = $id
