What potential pitfalls can arise from not using a template system in PHP for community building?

Without using a template system in PHP for community building, it can become challenging to maintain a consistent design across multiple pages, leading to a disorganized and unprofessional appearance. Additionally, it can make it difficult to separate the presentation layer from the business logic, resulting in a tangled mess of code that is hard to manage and update. To solve this issue, it is recommended to implement a template system such as Smarty or Twig in PHP. These template engines allow for the separation of the presentation layer from the business logic, making it easier to maintain a consistent design and update the codebase.

// Using the Smarty template engine in PHP
require_once('libs/Smarty.class.php');

$smarty = new Smarty;

$smarty->assign('title', 'Welcome to our Community');
$smarty->assign('content', 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.');

$smarty->display('index.tpl');
