How can PHP developers ensure proper hierarchy and structure when including subcategories within main category pages using switch statements?

To ensure proper hierarchy and structure when including subcategories within main category pages using switch statements, PHP developers can create a nested switch statement where the main category is checked first and then the subcategories are checked within the corresponding main category case. This approach helps maintain a clear and organized structure for handling different category and subcategory combinations.

$category = "main_category";
$subCategory = "sub_category";

switch($category) {
    case "main_category":
        switch($subCategory) {
            case "sub_category":
                // Code for displaying subcategory content
                break;
            default:
                // Default case for subcategories under main category
        }
        break;
    default:
        // Default case for main categories
}
