Are there any specific PHP functions or techniques that can help streamline the process of managing and displaying news articles on a website?

Managing and displaying news articles on a website can be streamlined by using PHP functions like `file_get_contents` to fetch article data from a database or external source, `json_decode` to parse the data into a usable format, and `foreach` loops to iterate through and display the articles on the webpage.

<?php
// Fetch article data from a database or external source
$articles_json = file_get_contents('articles.json');
$articles = json_decode($articles_json, true);

// Display articles on the webpage
foreach ($articles as $article) {
    echo '<h2>' . $article['title'] . '</h2>';
    echo '<p>' . $article['content'] . '</p>';
}
?>
