how to using file() save as??

[yuan]

Firstly i using notepad to save a xml file as UTF-8 encoding

After that i write another php file that using file() like:

$file = fopen("a.xml", "w");
   if(fwrite($file, $content)){ 
      echo "Success"; 
   } else {
      echo "Fail";
   }

it can succesfully save my text to xml file, but it also change my file type to Unicode encoding, so have any idea to control fwrite not change my file encoding type?

p/s: my text will include multilanguage

maybe you'd have more luck with binary write, add a b to the write option:

$file = fopen("a.xml", "wb");
