PHP function "return" is not returned

This is a little strange for me. PHP is my forte, and I can usually find out any problem I am having.

I have a user structure that I have been using for many years. I made a commitment to rewrite it, and I am doing essentially the same thing as before. The problem is the following build:

function ModPages_GetPage() {
    $page = ModPages_GetPageByName($_GET['page_name']);
    if($page != false) {
        include(TPL_DIR.'pages/pages.view.php');
    } else {
        ErrorMessage('Invalid Page', 'The selected page could not be found.');
    }
}


function ModPages_GetPageByName($page_name = null) {
    $db = new Database;
    $query = '
        SELECT *
        FROM pages
        WHERE page_name = "'.CleanStr($page_name).'"
            AND page_enabled = "yes"
        LIMIT 1
        ';
    $page = $db->GetRow($query);

    return $page;
}

This code is called with "home" for the value $_GET['page_name']. The call ModPages_GetPageByName()works fine, but the value $pageis ModPages_GetPage()not set to. In fact, any debug statements that were entered after this call do not display anything.
