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
<rss version="2.0">
<channel>
<item id="1">
<user><user_id>1</user_id><user_name/><user_pass>123</user_pass><real_name>木头</real_name></user>
<title>1</title>
<link>http://www.xxx.com</link>
<description>id:1,user_name:,pass:123,real_name:木头</description>
</item>
<item id="2">
<user><user_id>2</user_id><user_name/><user_pass>456</user_pass><real_name>小木头</real_name></user>
<title>2</title>
<link>http://www.xxx.com</link>
<description>id:2,user_name:,pass:456,real_name:小木头</description>
</item>
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'])
