Warning: domxml_open_file() [function.domxml-open-file]: Unsupported encoding GBK in /home/apache/htdocs/mainpage.php on line 322

xml目录的的xml文件都是 <?xml version="1.0" encoding="GBK"?>

系统: Solaris 10 x86, apache1.3.37, php 4.4.6 ,libiconv 1.11

另：如果把xml文件的encoding="GBK"改成 encoding="utf8"显示正常

如何解决呢？ 谢谢
