yes, not that it would be inherently wrong to do it that way, it is that 
tmpfile() already offers the file handle, so you can rewind() and put the 
contents in your destination file:


$destinationPath = tempnam(__DIR__, '.destination.');
$tempHandle = tmpfile();

# ... operate on $tempHandle ...
fwrite($tempHandle, "hello world\n");

rewind($tempHandle);
$result = file_put_contents($destinationPath, $tempHandle);
fclose($tempHandle);


Why move the temporary file when it is already a temporary file, right?
