How can developers ensure compatibility of PHP template engines with different PHP versions, such as PHP 7.2 to PHP 8.3?

To ensure compatibility of PHP template engines with different PHP versions, developers should regularly update their template engine libraries to support the latest PHP versions. This involves checking for deprecated features, updating syntax to adhere to newer PHP standards, and testing the template engine with various PHP versions to catch any compatibility issues. 

// Example code snippet of updating a template engine library to ensure compatibility with PHP 8.3

// Before making any changes, ensure the current template engine library supports PHP 8.3
// Update any deprecated functions or syntax to align with PHP 8.3 standards
// Test the template engine with PHP 8.3 to verify compatibility

// Updated code snippet for PHP 8.3 compatibility
// Assuming $templateEngine is the instantiated template engine object
$templateEngine->render('template_file.php', ['data' => $data]);
