How can PHP developers ensure that older news articles are properly archived and not displayed on the front page of a website?

To ensure that older news articles are properly archived and not displayed on the front page of a website, PHP developers can add a condition in their code to check the publication date of each article. If the publication date is older than a certain threshold (e.g. 30 days), the article should not be displayed on the front page.

// Check if the article publication date is older than 30 days
if(strtotime($article['publication_date']) < strtotime('-30 days')) {
    // Do not display the article on the front page
} else {
    // Display the article on the front page
}
