用Pear自動生成xml文件

需要安装两个组件XML/Serializer，XML/Util 代码如下：

 $employees = array(
    array(
   'name' => 'Jimi',
   'department' => 'Sales',
   'email' =>
    ),
    array(
   'name' => 'Cindy',
   'department' => 'Financial',
   'email' =>
    ),
    array(
   'name' => 'Ruby',
   'department' => 'Marketing',
   'email' =>
    )
 );

 require_once 'XML/Serializer.php';
  // 初始化
  $serializer = new XML_Serializer(array(
    "indent"          => "\t",        // 缩进, 也可为空格
    "linebreak"       => "\n",        // 换行符
    "typeHints"       => false,       // 附带每个节点的 PHP 类型
    "addDecl"         => true,        // 加入 XML 文档头
    "encoding"        => "UTF-8",     // 文档编码
    "rootName"        => "employees", // 根节点名称
    "defaultTagName"  => "employee"   // 默认节点名称
  ));

  $serializer->serialize($employees);

  header('Content-Type: application/xml');

  echo $serializer->getSerializedData();
