Are there any specific coding practices or conventions to follow when using PHP to dynamically change content on a webpage?

When dynamically changing content on a webpage using PHP, it is important to separate your PHP logic from your HTML markup to maintain clean and readable code. One common practice is to use PHP to fetch data from a database or external source, then use loops or conditionals to dynamically generate HTML content based on that data.

<?php
// Fetch data from database or external source
$data = getData();

// Loop through data to generate HTML content
foreach ($data as $item) {
    echo "<div class='item'>";
    echo "<h2>{$item['title']}</h2>";
    echo "<p>{$item['content']}</p>";
    echo "</div>";
}
?>
