------Solution--------------------
Put it in your project folder. It is currently outside the root directory.
------Solution--------------------
Your program is F:\APMServ5.2.6\APMServ5.2.6\www\htdocs\newfile.php.
Your files are in C:\Users\Administrator\Desktop\PHP.txt.

So access to PHP.txt requires

$FN = ' c:/users/administrator/desktop/php.txt ';
$file = fopen ($FN, "R");
$filesize = FileSize ($FN);
Echo fread ($file, $filesize);
Fclose ($file);
