php输出UTF-8格式XML文件中文乱码问题（含asp,asp.net,jsp代码）

下面是asp.net,php,jsp等语言在输出utf-8是需要在输出开始添加三个字节的内容，不让输出的文件会有一定的问题，希望对大家有所帮助。

Using ASP.NET C#

      Response.ContentType="text/xml; characterset=utf-8" ;
      Response.BinaryWrite( new byte[]{0xEF,0xBB,0xBF} );
       // Now write your XML data to output stream  http://www.my400800.cn
  

Using ASP.NET VB

      Response.ContentType="text/xml"
      Dim UTFHeader() As Byte ={&HEF,&HBB,&HBF}
      Response.BinaryWrite(UTFHeader)
      ' Now write your XML data to output stream
  

Using PHP

      header ( 'Content-type: text/xml' );
      echo pack ( "C3" , 0xef, 0xbb, 0xbf );
      // Now write your XML data to output stream
  

Using ASP

      Response.ContentType="text/html"
      Response.AddHeader"Content-Type","text/html;charset=UTF-8"
      Response.CodePage=65001
      Response.CharSet="UTF-8"
      Response.BinaryWrite( chrb(239) )
      Response.BinaryWrite( chrb(187) )
      Response.BinaryWrite( chrb(191) )
      ' Now write your XML data to output stream
  

Using JSP

          response.setContentType( "text/xml; charset=UTF-8" );
          OutputStream outs = response.getOutputStream();
          outs.write( new byte[]{(byte)0xEF,(byte)0xBB,(byte)0xBF} );
          outs.flush();
      // Now write your XML data to output stream
  

Using ColdFusion

        context = getPageContext();
        response = context.getResponse().getResponse();
        out= response.getOutputStream();

        out.write(239);
        out.write(187);
        out.write(191);
      // Now write your XML data to output stream
  

Using ROR

      utf8_arr = [0xEF,0xBB,0xBF]
      utf8_str = utf8_arr.pack("c3")
      # Now write your XML data to output stream
