On Windows that ought to work as it is.  On Linux/Unix, you will have to get a directory listing, make an UPPERCASE (or lowercase) comparison.  Note that you don't change the case of the file name that is read from the directory listing or it won't match the actual file name when you try to read it.


/* From http://us3.php.net/manual/en/function.readdir.php */
$filename = strtoupper($filename);
/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle))) {
    if($filename == strtoupper($file)){
        readfile($file);
        } else {
        ......
        }
    }
