What are some best practices for incorporating PHP functions with return values in a CMS environment?

When incorporating PHP functions with return values in a CMS environment, it is important to ensure that the function is properly integrated with the CMS structure and that the return value is utilized effectively within the CMS templates or modules. Best practices include creating modular functions that can be easily called from various parts of the CMS, using appropriate error handling to prevent issues with the return value, and documenting the function clearly for future reference.

// Example of a PHP function with return value in a CMS environment
function get_page_title($page_id) {
    // Retrieve the page title from the CMS database based on the page ID
    $title = get_title_from_database($page_id);

    // Perform any necessary processing or error handling
    if ($title) {
        return $title;
    } else {
        return "Page Not Found";
    }
}

// Example of how to use the function in a CMS template
$page_id = 123;
$page_title = get_page_title($page_id);
echo "<h1>{$page_title}</h1>";
