What role does a template engine like Smarty play in simplifying the integration of complex HTML structures into PHP code for tools like PHPGenerator?

When integrating complex HTML structures into PHP code, it can be challenging to maintain readability and manageability. Template engines like Smarty help simplify this process by separating the presentation layer from the business logic, making it easier to work with complex HTML structures in PHP code. By using Smarty, developers can create templates with placeholders for dynamic content, making it easier to update and maintain the code.

// Example of using Smarty template engine with PHPGenerator

require_once('smarty/libs/Smarty.class.php');

$smarty = new Smarty();

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

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