What are the potential drawbacks or limitations of using includes in PHP for common elements like menus and footers, and how can these be mitigated or avoided?

One potential drawback of using includes in PHP for common elements like menus and footers is that it can lead to performance issues if there are too many includes on a single page. This can slow down the loading time of the page. To mitigate this, you can use PHP's output buffering to capture the output of the included files and then include them all at once. 

<?php
ob_start();
include 'menu.php';
$menu = ob_get_clean();

ob_start();
include 'footer.php';
$footer = ob_get_clean();
?>

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
</head>
<body>
    <?php echo $menu; ?>
    
    <!-- Page content goes here -->
    
    <?php echo $footer; ?>
</body>
</html>
