"100 points for help" xml_parse_into_struct function parsing xml, Chinese garbled
The test code is as follows:

$xmldata = '
 
 
 
 
  
  Chinese
 
  ';
$parser = xml_parser_create (' UTF-8 ');
$vals = Array ();

Xml_parse_into_struct ($parser, $xmldata, $vals);
Xml_parser_free ($parser);

Print_r ($vals);

PHP version is 5.4.20

In the conversion result, the Chinese part is garbled.

Ask everyone, there is no one who has encountered this problem, how to solve ... Thank you!
------Solution--------------------
Obviously your program file when the GBK
$xmldata = ' Chinese ';
$xmldata = Iconv (' GBK ', ' utf-8 ', $xmldata);


------Solution--------------------
In fact, you iconv transcoding is also possible
But my side of the show is normal, no garbled estimate is the wrong browser encoding
