content-type added to php copy, changes file size , adds content-type to start of file

Hello Gurus, I have an issue, that I am trying to figure out if it is an Apache config issue or a PHP issue. I have written a script to upload file to a directory on my RH7.0 Linux Apache server. directory has been chmod 777. I have a problem with my php uploads. the content-type is added at the beginning of uploaded file. this makes file useless on server. here is my code for my upload page. <?php $archive_dir="../test"; if ($upload) { $filename = basename($userfile_name); if(!copy($userfile, "$archive_dir/$filename")) die ("$filename not copied! - Error!"); echo "File $filename Uploaded"; } ?> <table border="0" width="751"> <tr> <td> <form method="post" enctype="multipart/form-data" action="<? echo $PHP_SELF ?>"> Upload file! <input type="file" name="userfile"> <input type="SUBMIT" name="upload" VALUE="upload"> </form> </td> </tr> </table> Any thoughts would be appreciated. wade
