In PHP, what are some best practices for handling template variables within functions?

When handling template variables within functions in PHP, it is best practice to pass the variables as parameters to the function rather than relying on global variables. This ensures better encapsulation and reusability of the function. Additionally, it is recommended to validate the input variables within the function to ensure they are of the expected type and format. 

function renderTemplate($title, $content) {
    // Validate input variables
    if (!is_string($title) || !is_string($content)) {
        throw new InvalidArgumentException('Invalid input data');
    }

    // Template rendering logic using $title and $content
}
