In what scenarios would it be beneficial to use a pre-existing template engine like Smarty instead of creating a custom template system in PHP?

Using a pre-existing template engine like Smarty can be beneficial when you want to separate the presentation logic from the business logic in your PHP application. This can make your code more maintainable and easier to work with for designers and developers. Additionally, template engines like Smarty often come with built-in features for caching, escaping, and debugging, which can save you time and effort in developing these functionalities from scratch. 

// Example of using Smarty template engine in PHP

// Include the Smarty library
require_once('smarty/Smarty.class.php');

// Create a new instance of Smarty
$smarty = new Smarty();

// Assign variables to the template
$smarty->assign('title', 'Welcome to my website');
$smarty->assign('content', 'This is the content of the page');

// Display the template
$smarty->display('template.tpl');
