What are the potential pitfalls of dynamically generating HTML elements in PHP based on database values?

Potential pitfalls of dynamically generating HTML elements in PHP based on database values include security vulnerabilities such as SQL injection, cross-site scripting (XSS), and potentially poor performance due to excessive database queries. To mitigate these risks, it is important to properly sanitize and validate the database values before using them to generate HTML elements. 

<?php
// Example of sanitizing database values before generating HTML elements

// Retrieve database values
$db_values = get_values_from_database();

// Sanitize and validate the values
$sanitized_values = array_map('htmlspecialchars', $db_values);

// Generate HTML elements
foreach ($sanitized_values as $value) {
    echo "<div>" . $value . "</div>";
}
?>
