function get_categories($id) {
    
    global $cat_info, $config, $PHP_SELF;
    
    if( ! $id ) return;
    
    $parent_id = $cat_info[$id]['parentid'];
    
    if( $config['allow_alt_url'] == "yes" ) $list = "<span class=\"tag\"><a href=\"" . $config['http_home_url'] . get_url( $id ) . "/\">{$cat_info[$id]['name']}</a></span>";
    else $list = "<span class=\"tag\"><a href=\"$PHP_SELF?do=cat&amp;category={$cat_info[$id]['alt_name']}\">{$cat_info[$id]['name']}</a></span>";
    
    while ( $parent_id ) {
        
        if( $config['allow_alt_url'] == "yes" ) $list = "" . $list;
        else $list = "<span class=\"tag\"><a href=\"$PHP_SELF?do=cat&amp;category={$cat_info[$parent_id]['alt_name']}\">{$cat_info[$parent_id]['name']}</a></span>" . " &raquo; " . $list;
