PHP在页面输出XML的方法.避免乱码.

一般都是编码的问题了.
为了和FLASH交互,需要flashremoting , 或者传字符串 , xml了 .

PHP输出XML到页面的方式3种,记录一下:
1
<? php
header ( " Content-type: text/xml " );
echo   " <?xml version=\ " 1.0 \ "  encoding=\ " UTF - 8 \ " ?> " ;
echo   " <users> " ;
echo   " <user> " ;
   
echo   " <name> " ;
    
echo   " 小小菜鸟 " ;
   
echo   " </name> " ;
   
echo   " <age> " ;
    
echo   " 24 " ;
   
echo   " </age> " ;
   
echo   " <sex> " ;
    
echo   " " ;
   
echo   " </sex> " ;
echo   " </user> " ;
echo   " <user> " ;
   
echo   " <name> " ;
    
echo   " 艳艳 " ;
   
echo   " </name> " ;
   
echo   " <age> " ;
    
echo   " 23 " ;
   
echo   " </age> " ;
   
echo   " <sex> " ;
    
echo   " " ;
   
echo   " </sex> " ;
echo   " </user> " ;
echo   " </users> " ;
?>

<? php
header ( " Content-type: text/xml " );
echo   " <?xml version=\ " 1.0 \ "  encoding=\ " UTF - 8 \ " ?> " ;
echo   " <users><user><name>小小菜鸟</name><age>24</age><sex>男</sex></user><user><name>艳艳</name><age>23</age><sex>女</sex></user></users> " ;
?>

<? php
/*
用PHP的DOM控件来创建XML输出
设置输出内容的类型为xml
*/
header ( ' Content-Type: text/xml; ' );
// 创建新的xml文件
$dom   =   new  DOMDocument( ' 1.0 ' ,   ' utf-8 ' );

// 建立<response>元素
$response   =   $dom -> createElement( ' response ' );
$dom -> appendChild( $response );

// 建立<books>元素并将其作为<response>的子元素
$books   =   $dom -> createElement( ' books ' );
$response -> appendChild( $books );

// 为book创建标题
$title   =   $dom -> createElement( ' title ' );
$titleText   =   $dom -> createTextNode( ' PHP与AJAX ' );
$title -> appendChild( $titleText );

// 为book创建isbn元素
$isbn   =   $dom -> createElement( ' isbn ' );
$isbnText   =   $dom -> createTextNode( ' 1-21258986 ' );
$isbn -> appendChild( $isbnText );

// 创建book元素
$book   =   $dom -> createElement( ' book ' );
$book -> appendChild( $title );
$book -> appendChild( $isbn );

// 将<book>作为<books>子元素
$books -> appendChild( $book );

// 在一字符串变量中建立XML结构
$xmlString   =   $dom -> saveXML();

// 输出XML字符串
echo   $xmlString ;

?>
