php生成rss文件求改进
我写了一个php利用DOMDocument 组件生成rss文件的代码，但是感觉太过于臃肿，想封装成一个类但是一直没成功，特来请教
生成后rss大体是这样的
1 123 木头
1
http://www.xxx.com
id:1,user_name:,pass:123,real_name:木头
2 456 小木头
2
http://www.xxx.com
id:2,user_name:,pass:456,real_name:小木头
当然代码太过于冗余
$doc = new DOMDocument('1.0','utf-8');
$doc->formatOutput = true;
//创建标签
//创建rss标签
$rss = $doc->createElement('rss');
//创建channel下面的标签
$channel = $doc->createElement('channel');
$ctitle = $doc->createElement('title');
$clink = $doc->createElement('link');
$cdescription = $doc->createElement('description');
foreach ($arr as $key => $val) {
//创建item标签
$item = $doc->createElement('item');
//创建item下的子标签标签
$user = $doc->createElement('user');
$ititle = $doc->createElement('title');
$ilink = $doc->createElement('link');
$idescription = $doc->createElement('description');
//创建user标签
$user_id = $doc->createElement('user_id');
$user_name = $doc->createElement('user_name');
$user_pass = $doc->createElement('user_pass');
$real_name = $doc->createElement('real_name');
/*这里是需要数据库循环调用的地方*/
//创建内容
//创建item下面的标签的内容
$c_ititle = $doc->createTextNode($val['user_id']);
$c_ilink = $doc->createTextNode('http://www.xxx.com');
$c_idescription = $doc->createTextNode('id:'.$val['user_id'].',user_name:'.$val['user_name'].',pass:'.$val['pass'].',real_name:'.$val['real_name']);
//创建user下面的标签的内容
$c_user_id = $doc->createTextNode($val['user_id']);
$c_user_name = $doc->createTextNode($val['user_name']);
$c_user_pass = $doc->createTextNode($val['pass']);
$c_real_name = $doc->createTextNode($val['real_name']);
//创建item属性值
$a_id = $doc->createTextNode($val['user_id']);
//创建属性
$attributes = $doc->createAttribute('id');
/*这里是需要数据库循环调用的地方*/
//item一级标签的元素内容继承
$ititle->appendChild($c_ititle);
$ilink->appendChild($c_ilink);
$idescription->appendChild($c_idescription);
//user一级标签的元素内容继承
$user_id->appendChild($c_user_id);
$user_name->appendChild($c_user_name);
$user_pass->appendChild($c_user_pass);
$real_name->appendChild($c_real_name);
/*这里是需要数据库循环调用的地方*/
//继承
$channel->appendChild($item);
//item一级标签的标签继承
$item->appendChild($user);
$item->appendChild($ititle);
$item->appendChild($ilink);
$item->appendChild($idescription);
//id=1
$attributes->appendChild($a_id);
//
$item->appendChild($attributes);
//item一级标签的标签继承
$user->appendChild($user_id);
$user->appendChild($user_name);
$user->appendChild($user_pass);
$user->appendChild($real_name);
