生成xml源代码：
$dom = new domdocument();
    if(!$dom)
    {
        printf(构造xml失败!);
        return -3999;
    }
if(false == ($dom->load($filename)))
    {
        add_root();
        if(false == ($dom->load($filename)))
        {
            return -3999;
        }
    }
//引用root根节点
    $f_node = $dom->getelementsbytagname($parent_node)->item(0);
    if(!$f_node)
    {
        $root = $dom->getelementsbytagname(root)->item(0);
        //创建父节点
        $f_node = $dom->createelement($parent_node);
        $f_node = $root->appendchild($f_node);
    }    
    //创建节点
    $item_node = $dom->createelement($node);
    $item_node = $f_node->appendchild($item_node);
    $item_value = $dom->createtextnode($value);
    $item_node->appendchild($item_value);
