What are some potential pitfalls of using a custom TPL engine in PHP, as opposed to using a pre-existing template engine like Smarty?

Potential pitfalls of using a custom TPL engine in PHP include reinventing the wheel, lack of community support, and potential security vulnerabilities. It is often more efficient and secure to use a pre-existing template engine like Smarty, which is widely used and tested by the community. 

// Example of using Smarty template engine
require_once('libs/Smarty.class.php');

$smarty = new Smarty;
$smarty->template_dir = 'templates';
$smarty->compile_dir = 'templates_c';

$smarty->assign('name', 'John Doe');
$smarty->display('index.tpl');
