$ Data = file_get_contents ("D: \ works \ logo.png"); // original file path
$ Ifp = fopen(export Test.png "," wb "); // open a new file. If no file exists, create the file again.
Fwrite ($ ifp, $ data); // write the stream of the original file to the new file.
Fclose ($ ifp); // closes the file operation flow
?>
