My output for Rasmus Lerdorf is not valid and I do not know why it is not valid

I do not know what is wrong with my echo. Output looks Ok when you are looking it from preview.

index.php 
<?php

//Place your code below this comment
$firstName = 'Rasmus';
$lastName = 'Lerdorf';
$fullname = $firstName . ' ' . $lastName;
echo $fullname . ' was the orginal creator of PHP' . "\n";
?>
