What are the potential pitfalls of changing the title of a webpage dynamically using PHP includes?

One potential pitfall of changing the title of a webpage dynamically using PHP includes is that it may lead to confusion or errors if not implemented correctly. To avoid this, you can set a variable in each included file that contains the desired title and then use this variable in the main file to dynamically update the title.

// In each included file, set a variable with the desired title
$title = "Page Title";

// In the main file, use the variable to dynamically update the title
<title><?php echo $title; ?></title>
