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





1123木头
1
http://www.xxx.com
id:1,user_name:,pass:123,real_name:木头




2456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);
}
