What are the performance implications of dynamically generating a menu by copying HTML code from a CMS in PHP?

Dynamically generating a menu by copying HTML code from a CMS in PHP can lead to performance issues due to the overhead of processing and rendering the copied HTML code each time the menu is displayed. To improve performance, it is recommended to generate the menu dynamically using PHP functions and data from the CMS, rather than copying static HTML code. This approach allows for more flexibility, easier maintenance, and better performance.

<?php
// Example of dynamically generating a menu in PHP
$menuItems = array(
    'Home' => '/',
    'About' => '/about',
    'Services' => '/services',
    'Contact' => '/contact'
);

echo '<ul>';
foreach ($menuItems as $label => $url) {
    echo '<li><a href="' . $url . '">' . $label . '</a></li>';
}
echo '</ul>';
?>
