Improve the rss file generated by php

I wrote a php code that uses the DOMDocument & nbsp; component to generate an rss file. However, the code is too bloated and I want to encapsulate it into a class but it has never been successful, the generated rss is generally like this & lt; rss & nbsp; version = "2.0" & gt; & lt; channel & gt; & lt; improve the rss file generation by item & n php
I wrote a php code that uses the DOMDocument component to generate an rss file, but it feels too bloated. I want to encapsulate it into a class but it has never been successful. please refer
The generated rss is generally like this.





1 123 Wood
1
Http://www.xxx.com
Id: 1, user_name:, pass: 123, real_name: Wood




2 456 Small Wood
2
Http://www.xxx.com
Id: 2, user_name:, pass: 456, real_name: xiaowood





Of course the code is too redundant



$ Doc = new DOMDocument ('1. 0', 'utf-8 ');
$ Doc-> formatOutput = true;


// Create a tag
// Create an rss label
$ Rss = $ doc-> createElement ('RSS ');
// Create a tag under the channel
$ Channel = $ doc-> createElement ('channel ');
$ Ctitle = $ doc-> createElement ('title ');
$ Clink = $ doc-> createElement ('link ');
$ Cdescription = $ doc-> createElement ('Description ');






Foreach ($ arr as $ key => $ val ){
// Create an item tag
$ Item = $ doc-> createElement ('ITEM ');
// Create a sub-label under item
$ User = $ doc-> createElement ('user ');
$ Ititle = $ doc-> createElement ('title ');
$ Ilink = $ doc-> createElement ('link ');
$ Ideelement = $ doc-> createElement ('Description ');
// Create a user tag
$ User_id = $ doc-> createElement ('User _ id ');
$ User_name = $ doc-> createElement ('User _ name ');
$ User_pass = $ doc-> createElement ('User _ pass ');
$ Real_name = $ doc-> createElement ('Real _ name ');
/* Here is the place where the database needs to be called cyclically */
// Create content
// Create the tag content under the item
$ C_ititle = $ doc-> createTextNode ($ val ['User _ id']);
$ C_ilink = $ doc-> createTextNode ('http: // www.xxx.com ');
$ C_ide.pdf = $ doc-> createTextNode ('Id :'. $ val ['User _ id']. ', user_name :'. $ val ['User _ name']. ', pass :'. $ val ['pass']. ', real_name :'. $ val ['real _ name']);
// Create the tag content under the user
$ 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']);
// Create the item property value
$ A_id = $ doc-> createTextNode ($ val ['User _ id']);


// Create attributes
$ Attributes = $ doc-> createAttribute ('id ');
/* Here is the place where the database needs to be called cyclically */
// Inherit the element content of the item-level label
$ Ititle-> appendChild ($ c_ititle );
$ Ilink-> appendChild ($ c_ilink );
$ IDevice-> appendChild ($ c_idevice );
// Inherit the element content of the user-level label
$ User_id-> appendChild ($ c_user_id );
$ User_name-> appendChild ($ c_user_name );
$ User_pass-> appendChild ($ c_user_pass );
$ Real_name-> appendChild ($ c_real_name );

// Inherit
$ Channel-> appendChild ($ item );
// Tag inheritance of item-level labels
$ Item-> appendChild ($ user );
$ Item-> appendChild ($ ititle );
$ Item-> appendChild ($ ilink );
$ Item-> appendChild ($ ide.pdf );
// Id = 1
$ Attributes-> appendChild ($ a_id );
//
$ Item-> appendChild ($ attributes );


// Tag inheritance of item-level labels
$ User-> appendChild ($ user_id );
$ User-> appendChild ($ user_name );
$ User-> appendChild ($ user_pass );
$ User-> appendChild ($ real_name );
