In what scenarios would it be more beneficial to create a custom system for organizing PHP code instead of using a template system like Smarty?

In scenarios where you need more flexibility and control over how your PHP code is organized and executed, it may be more beneficial to create a custom system for organizing your code instead of using a template system like Smarty. This could be particularly useful if you have unique requirements or complex logic that cannot be easily handled by a template system. By creating a custom system, you can tailor the organization and execution of your PHP code to better suit your specific needs.

// Custom system for organizing PHP code

// Example of custom code organization
function processUserData($data) {
    // Process user data here
}

function displayUserDetails($user) {
    // Display user details here
}

// Example of using the custom code organization
$userData = getUserData();
$processedData = processUserData($userData);
displayUserDetails($processedData);
