Read and write configuration files the format xml with Zend

1. Read ini file.

I have a configuration file /application/configs/db.ini as follows:

<?xml version="1.0" encoding="UTF-8"?>
<configdata>
 <infomation>
  <webhost>www.example.com</webhost>
  <database>
   <adapter>pdo_mysql</adapter>
   <params>
    <host>localhost</host>
    <username>root</username>
    <password>root</password>
    <dbname>zftraining</dbname>
   </params>
  </database>
 </infomation>
 <data extends="infomation">
  <webhost>www.example.com</webhost>
  <database>
   <adapter>pdo_mysql</adapter>
   <params>
    <host>localhost</host>
    <username>vanlanh</username>
    <password>123456</password>
    <dbname>zftraining</dbname>
   </params>
  </database>
 </data>
</configdata>

We use the class to read file Zend_Config_Xml db.xml

  
 public function xmlAction(){
  $xml = CONFIG_PATH . '/db.xml';
  $section = 'data';
  $config = new Zend_Config_Xml($xml, $section);
  echo '<br>' . $config->webhost;
  echo '<br>' . $config->database->adapter;
  echo '<br>' . $config->database->params->username;
  echo '<br><hr>';
  echo '<pre>';
  print_r($config->toArray());
  echo '</pre>';
 }

Output:

www.example.com
pdo_mysql
vanlanh
Array
(
    [webhost] => www.example.com
    [database] => Array
        (
            [adapter] => pdo_mysql
            [params] => Array
                (
                    [host] => localhost
                    [username] => vanlanh
                    [password] => 123456
                    [dbname] => zftraining
                )

        )

)

2.Write xml file

 public function writeXmlAction(){
  $data = array(
    'global'=>array(
     'smtp'=>array(
      'parameters'=>array(
       'host'  => "smtp.example.com",
       'port'  => "587",
       'username' => "jeky11",
       'password' => "hyd3",
       'security' => "tls",
       ) 
      )   
     ),
      'data'=>array(
       'version' => "1.1"
     )
    );
  $config = new Zend_Config_Writer_Xml();
  $filename = CONFIG_PATH . '/my01.xml';
  $objConfig = new Zend_Config($data);
  $config->write($filename,$objConfig);
 }

My01.xml output file:

<?xml version="1.0"?>
<zend-config xmlns:zf="http://framework.zend.com/xml/zend-config-xml/1.0/">
  <global>
    <smtp>
      <parameters>
        <host>smtp.example.com</host>
        <port>587</port>
        <username>jeky11</username>
        <password>hyd3</password>
        <security>tls</security>
      </parameters>
    </smtp>
  </global>
  <data>
    <version>1.1</version>
  </data>
</zend-config>
