Why does SplFileObject always seems to return an extraneous, final empty string as an extra last line of file.

If I have a file with only one line of text and run this code

try {
$file = new SplFileObject("./one.txt");

} catch (Exception $e) {
echo $e->getMessage() . "\n";
}

foreach($file as $line_no => $contents) {

echo "line number " . $line_no . " is: " . $contents;

}

I get two lines of output:
line number 0 is: one
line number 1 is:

The file one has one line of text, the word "one". I'm running this on Linux Mint 17 with PHP 5.5.9.

Thanks
