php5 在 windows 下运行时，不需要在 php.ini 里声明 php_domxml.dll，加个分号注释起来就行了。
If you use PHP 5 in windows, you don't need to declare php_domxml.dll in your php.ini file.
so u can give comment in the line php_domxml.dll in your php.ini file.
you only need to comment it out, but do not delete the php_domxml.dll file in the ext directory.
