What are the advantages and disadvantages of allowing PHP code execution in .tpl files within a PHP environment?

Allowing PHP code execution in .tpl files within a PHP environment can provide flexibility in creating dynamic templates. However, it can also introduce security vulnerabilities if not properly sanitized or validated. It is recommended to use a templating engine like Smarty or Twig to separate PHP logic from presentation, ensuring better code organization and security. 

// Example using the Smarty templating engine
$smarty = new Smarty;
$smarty->template_dir = 'templates';
$smarty->compile_dir = 'templates_c';
$smarty->config_dir = 'configs';
$smarty->cache_dir = 'cache';

// 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('index.tpl');
