How can PHP developers ensure clean and efficient HTML output when displaying database entries?

When displaying database entries in HTML, PHP developers can ensure clean and efficient output by separating the PHP logic from the HTML markup. This can be achieved by using PHP loops to iterate over the database results and generate the necessary HTML elements dynamically. Additionally, developers should sanitize user input to prevent any potential security vulnerabilities.

<?php
// Assume $results is an array of database entries

foreach ($results as $result) {
    $sanitizedData = htmlspecialchars($result['data'], ENT_QUOTES, 'UTF-8');
    echo "<div>{$sanitizedData}</div>";
}
?>
